During a trip to the Czech Republic this summer, Bret Love desperately wanted to escape the crowds at Prague Castle but couldn’t. He was stuck in a Vltava River of humanity.

“There were thousands and thousands and thousands of people jostling for space,” said the co-founder of Green Global Travel. “You start to feel like cattle being herded.”

No matter what you call it — overtourism, overbooked or a foreign invasion — it’s the same squeeze: A handful of destinations around the world are under siege by too many tourists. The stampede is having a deleterious effect on the culture, environment and spirit of these places. Locals are getting pushed out. Foundations are crumbling. Tourists are complaining about other tourists.

“You try to keep these cities livable for the residents,” said Martha Honey, executive director of the Center for Responsible Travel, “but overtourism is killing these neighborhoods and the reasons we go there.”

Former Washington Post reporter Elizabeth Becker examined the consequences of rampant tourism in her expose, “Overbooked: The Exploding Business of Travel and Tourism.” The book’s 2013 release coincided with a tourism milestone: For the first time, travelers had logged a billion international trips in one year.

The issue is not the industry itself but the hordes of people who descend on one place during the same time period (often summer). Destinations that are ill-equipped for the masses can’t keep up with the demand, and everyone suffers for it. Becker equates the situation to a dinner party host who plans for 12 guests and 12,000 hungry diners show up.

Travelers can help ease the pressure by tweaking their trips. For instance, visit offseason, book tickets to major attractions in advance and venture beyond the historical core. Becker also recommends longer holidays of two weeks over short getaways of two to five days.

“You are planning your trip in a way that will be the least damaging,” she said. “Your footprint is going to be less.”

To further help beleaguered destinations, we singled out 10 spots buckling under the weight of too many feet and provided alternatives that are similar in all but one category: They could use more — not fewer — tourists.

Overbooked: Venice

As if sinking weren’t enough, the Italian city of canals and masquerade balls is drowning in tourists. More than 30 million people visit annually, swamping the local population of 50,000 and causing rifts between the two camps. Several years ago, UNESCO warned Venetian officials that the city could end up on its endangered list of heritage sites if they did not curb their enthusiasm for tourists — an estimated 60,000 a day during peak season. Officials responded with a raft of initiatives, such as relocating the cruise ship port to the mainland and banning new hotels in the historical city center. Venice also unveiled an awareness campaign last year called #EnjoyRespectVenezia, which encourages responsible behavior (e.g., do not picnic on church steps) and provides a daily meter of crowds (all red from June through mid-September). The city is also promoting Detourism, a movement that urges visitors to avoid beaten-to-a-pulp routes and to behave like a local.

Overlooked: Verona

To visit or not to visit, that is such a silly question. Of course you should. The Italian city 75 miles west of Venice is the setting of two Shakespeare plays. Bard fans can practice their lines beneath Juliet’s balcony while relationship-seekers can give her statue a hopeful tap instead of swiping right. Similar to Venice, the UNESCO World Heritage site comes with the requisite Old World charms, such as a piazza populated by statues of Greek gods, a performing arts venue inhabiting a Roman amphitheater and a 13th-century castle built to defend the Veronese from invaders. The destination is also known for its European Union-protected variety of rice, a mainstay on local menus. Follow the grain along La Strada del Riso Vialone Nano Veronese IGP — longhand for the Rice Route. For a wilder ride than a gondola, go rafting down the Adige River. Ask nicely and maybe your guide will sing “O Sole Mio.”

Overbooked: Machu Picchu

The 15th-century Incan site has survived the Spanish conquest, a scandal involving a Yale explorer and flooding, but its downfall could be tourists. In 2013, UNESCO, the United Nations Educational, Scientific and Cultural Organization, aired its concerns about the degradation of Peru’s top attraction. Among its myriad offenses: “Impacts of tourism/visitor/recreation.” In response, the government and UNESCO capped the number of daily visitors at 2,500. However, last year, 1.4 million people toured the ruins, a clear breach of the directive. To control the chaos, the government announced new restrictions last July, such as requiring accredited guides to accompany all visitors (no more independent wandering) and funneling hikers onto three established routes. Also gone: staying all day. You can buy a ticket for the morning or afternoon slot, but once your time is up, your visit is over.

Overlooked: Choquequirao

Machu Picchu and Choquequirao might as well be twins: Both ancient Incan cities are in Peru’s Andes Mountains and demonstrate the same architectural style and building techniques. They also have the same jumping-off point (the city of Cusco) and are accessible by multiday trek, though the Choquequirao Hike is more arduous than the Inca Trail. Despite the similarities, Choquequirao, which is three times larger than Machu Picchu, receives a tiny fraction of visitors — a dozen to 30 adventurers a day. Why the trickle? Maybe because the site is less-known: Archaeologists did not start excavating the ruins until the 1970s, more than a half-century after Machu Picchu was cleared. Or that it is less-developed. Only one-third of the site has been exposed. Or harder to reach. (See above.) As part of an initiative to double tourism by 2021, the government has floated plans to build a road connecting the two sites, which sit about 40 miles apart, and install a cable car. But for now, only the hardiest souls can swing in the Cradle of Gold.

Overbooked: Barcelona

The capital of Catalonia is the most-visited city in Spain, drawing 32 million people, more than 30 times its population. In one municipal survey, residents blasted tourism as the second-worst urban ill after unemployment. Anti-tourist graffiti has started popping up, and locals have protested the loss of their home to foreign invaders. After the terrorist attack last August, the city experienced a slight dip in tourism, but it wasn’t enough to decongest La Rambla, the nearly mile-long pedestrian boulevard, or the buildings designed by famed Spanish architect Antoni Gaudí. In addition to land travelers, nearly 3 million passengers arrive by cruise ship annually, a surge officials hope to stem by relocating the port outside the city center by 2025. The current mayor, Ada Colau, won the election on her proposals to control unchecked tourism. Measures include fining Airbnb.com for renting unlicensed properties, raising the parking rate for coach buses idling at popular tourist spots and slowing the proliferation of hotel rooms, including banning new properties in the city’s congested hub.

Overlooked: Seville

Trade one Spanish capital for another. Seville is the cultural and business center of the Andalusian region, plus a great place to take flamenco for a spin. The city goes big with the world’s largest Gothic church, the Seville Cathedral, which brings guests closer to the heavens on a rooftop walk. The city claims more than just a one-name architect; it boasts its own regional style that blends Islamic and Christian aesthetics. Play I-Spy Mudejar around town: Look for vibrant glazed tiles with nature themes, rounded arches and carved wood ceilings. If you’re pressed for time, go straight to the Royal Alcázar, a palace complex with a strong Mudejar streak. Moorish influences — chickpeas, cumin, aubergine — appear in the tapas, too. Of course, the primo ingredient is jamon Iberico. Vegetarians who would rather meet the acorn-snuffling pigs than consume them can take a farm tour in the countryside. Or eat a Seville orange.

Overbooked: Reykjavik

Go ahead and wag a finger at Icelandair. The budget airline popularized the practice of adding a free stopover in Iceland en route to continental Europe. More recently, Wow Air, which started service in 2011, extended the perk to its passengers. The number of international air travelers has skyrocketed; visits between 2016 and 2017 grew 25 percent, to 2.2 million. Americans are the largest contingent, outnumbering the Icelandic population of 350,000. Most tourists congregate in Reykjavik and the southwest region, clogging the capital and the Golden Circle, the driving loop fizzing with geothermal features. The deluge has caused a shortage of hotel rooms. Airbnb has helped fill the vacuum, but the shift to short-term rentals has stressed the limited supply of units and caused rents to spike. To mitigate the housing crunch, the government has placed restrictions on Airbnb property owners. Closer to the airport, the Blue Lagoon, which attracts nearly a million guests each year, can often feel like a bumper car track with colliding bodies instead of automobiles.

Overlooked: Baffin Island

Baffin Island, in the way-north Canadian territory of Nunavut, is the fifth-largest isle in the world, a baker’s dozen spots ahead of Iceland. The landmass in the North Atlantic Ocean shares several characteristics with the Scandinavian country, such as fjords, the midnight sun, the northern lights, the Arctic Circle and, according to recent archaeology digs, Vikings. Though the Nunavut capital of Iqaluit is minuscule compared with Reykjavik, visitors can soak up the northern culture at the Nunatta Sunakkutaangit Museum, which specializes in Inuit art and artifacts, and during the Toonik Tyme Festival, a springtime celebration of tribal traditions including igloo-building, dog sledding and skijoring. Outside the city, take a deep plunge into the outdoors at several national parks. At Auyuittuq National Park, you can ski, hike on glaciers and ice fields, and climb Mount Thor, which has the world’s longest vertical drop. For less chilling activities (adrenaline-wise), scour Sirmilik National Park for such wildlife as narwhals, caribou, polar bears, ringed seals, belugas and killer whales. If you learn one phrase in Inuktitut, let it be this: “avatittinnik kamatsiarniq,” which means “respect and care for the land, animals and the environment.”

Overbooked: Mount Everest

The world’s tallest mountain, which straddles Nepal and Tibet, suffers from some of the same ills as urban centers: trash and traffic. To reach the summit, trekkers sometimes have to wait in lines as long as those for Disney World’s Space Mountain. Litter, including empty oxygen tanks, clutters the trail, and a stream of waste is threatening to rise up. Base camps can resemble a beach on Independence Day, the brightly colored tents blanketing the snowpacked ground. The crowds are endangering the environment as well as themselves: In 2014 and 2015, deadly avalanches took the lives of 16 Sherpas and 19 climbers, respectively. And yet the trekkers still come, including novices with little experience in high altitude adventures. Last year, the government issued a record number of climbing permits, nearly 375 permission slips for 43 international expedition teams. That figure does not include the porters and guides, who more than double the number.

Overlooked: Mount Toubkal

The tallest peak in Morocco’s Atlas mountains is a mouse compared with Asia’s lions, but it does dwarf most of the major mountains in the Americas, Europe and Oceana. Plus, it comes with a bonus bragging right: You can tell your ground-level friends that you have climbed the highest point in North Africa. Lee Thompson, co-founder of Flash Pack, a London-based tour company, says Toubkal is as mentally challenging as the ascent to the Everest base camp but is more accessible to hikers with less experience and more moderate fitness levels. The 13,671-foot-tall mountain sits within Toubkal National Park, about 40 miles south of Marrakesh. The climb takes about two days, and halfway up the mountain, you can carb- and mint tea-load in Sidi Chamharouch, a Berber settlement with a Muslim shrine. On summit day, you’ll wake with the roosters and trek 10 hours to reach your crowning achievement. You have earned that hammam.

Overbooked: Camino de Santiago

One of the world’s most popular pilgrimage routes, which dates to the Middle Ages, seems like an unlikely candidate for overtourism. The Way of Saint James comprises a spider’s web of routes that take weeks to complete by foot, bike or horseback. However, more than half of the pilgrims — religious and secular — follow the French Way, a 500-mile journey that starts in Saint-Jean-Pied-de-Port in the French Pyrenees and ends at Santiago de Compostela Cathedral in Galicia, Spain, where the saint is allegedly buried. According to the Pilgrims’ Welcome Office in Santiago de Compostela, more than 300,000 people completed the pilgrimage last year, a 10 percent increase from the last Holy Year in 2010. In August, the busiest month, the office registered 60,412 finishers, twice as many people as a decade ago. The crowds translate to lodging shortages in the small villages, inflated prices and compadres boisterous enough to disrupt the peace of a saint.

Overlooked: St. Cuthbert’s Way

Established in 1996, the long-distance walk in Scotland is much younger than Camino de Santiago, but it too has an old soul. The 62.5-mile trek follows the life trajectory of Saint Cuthbert, the venerated patron saint of Northern England. The sojourn starts in the Scottish Borders town of Melrose, where Cuthbert set off on his religious calling in A.D. 650, and ends on Holy Island, his RIP place and site of his original pilgrimage shrine off the Northumberland Coast. The route, which is marked with St. Cuthbert’s Cross symbols, takes four to six days to complete. For the final leg across the Pilgrims Path sands or the island causeway, check the tide charts in advance or you will be praying for a miracle. Depending on the season, you might see more baby animals than people. Watch for breeding birds from April through June, newborn lambs from March through May, and calves in spring and autumn.

Overbooked: Dubrovnik

“Game of Thrones” has been a boon for HBO and fantasy fiction fans but a burden for the Croatian city. The Pearl of the Adriatic had already been squirming beneath the crush of cruisers when the sword-wielding tourists showed up, searching for the real-life Westeros. The onslaught has even troubled UNESCO, which had designated the Old City a World Heritage site in 1979. The organization recommended limiting the number of visitors to 8,000 people a day; the newly elected mayor, Mato Frankovic, countered with a lower figure of 4,000. He has also promised to tackle the cruise-ship jam. During the high season, three to four ships often sail into port daily. As a remedy, the mayor proposed curbing the number of cruises during peak times and staggering arrivals. The plan could alleviate pressure on such key attractions as the Stradun, a pedestrian promenade, and the medieval walls, which bore the weight of more than 10,000 people on one day in August 2016. The city has also considered creating an app that will provide crowd updates and suggest alternatives with more wiggle room.

Overlooked: Rovinj

The Croatian fishing port shares the same coast as Dubrovnik and draws tourists and cruise ships during the summer, but not nearly as many as its southern neighbor. Typically, three or four ships tender per month — not day — during the summer. The town sits on the Istrian Peninsula in the Adriatic and was an island before the Venetians filled in the channel in 1763. The Italians, who twice controlled the city, have left their prints all over the place. You can see their influence on the Church of Saint Euphemia and the town square clock that is adorned with the Lion of Saint Mark symbol, as well as in the many restaurants serving pastas and pizza laced with truffles foraged from the nearby Motovun Forest. To visit the archipelago islands or the Istrian port town of Porec, catch a water taxi or ferry. Just be sure you don’t board the wrong boat and end up in Venice.

Overbooked: Amsterdam

Tourists outnumber residents by double-digit millions, so it’s no wonder the high of tourism has worn off. To reclaim the Dutch capital, officials are mulling or have executed several laws, such as doubling the tax on hotel rooms and banning short-term Airbnb rentals and souvenir shops in the historical center. They are also considering relocating the cruise-ship berth and passenger terminal away from the middle of the action, a move that will affect cruisers on more than 2,000 ocean liners and riverboats. In the red-light district, law enforcement officers have started ticketing bad behavior such as public drinking and littering. A new color-coded system will monitor crowds; a red signal could result in street closures, for example. To lure visitors out of the choked center, the tourism organization responsible for the City Card expanded benefits to include day trips outside the city, such as to Haarlem, Zaanse Schans and Keukenhof, where you can tiptoe through the tulip fields.

Overlooked: Ljubljana

Tulips, bikes and waterways define Amsterdam, but the trio also describe Ljubljana. The capital of Slovenia shares many of the same attributes as its western neighbor, such as the Volcji Potok Arboretum, which holds a tulip exhibit every April; a bike-share program with rentals and more than 5,450 cycling routes; and the Ljubljana River, which wriggles through marshes and the heart of the city. Ljubljana is more green than red: The European Commission crowned the city the European Green Capital in 2016, a distinction Amsterdam has never won. You can inhale the fresh air aboard Kavalirs (Gentle Helpers), the free public transport system that runs on electricity, and in Tivoli Garden, the city’s largest park. The Central Market is a feeding frenzy with an open-air and covered market, plus food shops and other retail. At the Open Market, which runs April through October, more than 30 chefs prepare local and international dishes. Show your love for Slovenia and pop into a bakery for a Ljubljana cake, which incorporates ingredients from around the country.

Overbooked: Rome

In Euromonitor International’s 2017 list of the top 100 cities, four Italian metro centers made the cut. Rome took 12th place; Milan, Venice and Florence were many leaps behind. The marketing research firm expects visitation numbers to surpass 10 million by 2020, but you doesn’t have to wait for the future to see the toll tourism has taken on the Eternal City. In 2015, the Spanish Steps closed for a year to reverse damage caused by too many touchy people. The renovation, which cost $1.7 million, removed stains, repaired broken pacing stones and re-leveled the steps. The lines to enter the city’s Roman ruins and museums are notorious. The Colosseum’s website, for once, states that the arena can accommodate up to 3,000 people at one time but warns, “This could lead to delays in access to the site, even for pre-booked visitors.” More than 2,000 fountains add a cool splash to the cityscape. To keep the water features clear of snacks and limbs, a new rule will fine anyone caught eating or drinking on the edges of 40 fountains or taking a dip in its waters.

Overlooked: Turin

Like Rome, the ghosts of Roman civilization haunt this Piemonte city in northern Italy. You can find them under your feet, on the cobblestone streets, and looming overhead, in the 16-sided towers bookending the Palatine Gate. Quadrilatero Romano, or the Roman Quarter, showcases the period’s signature grid as well as ancient wall ruins and the excavated remains of a Roman theater. The Royal Museums contain several institutions that track the city’s arc from Roman times to Italian unification in the 1800s. (Turin was the first capital of Uno Italy.) Among the complex’s cultural attractions: the Archaeological Museum; the Royal Garden, Armoury and Library; and the Chapel of the Holy Shroud, which reopened in September after a 28-year closure. Rome might be la dolce vita of vespas, but Turin is the headquarters of such dashing rides as Fiat and Alfa Romeo. The National Automobile Museum has amassed a collection of more than 200 vehicles from France, Britain, Germany, Poland, the Netherlands, Spain, the United States and, of course, Italy.

Overbooked: Cinque Terre

The daisy chain of five medieval villages along the Italian Riviera is wilting. Hordes of people arriving by train, cruise ship and motor coach are cramming into towns with limited space (the sea foils any expansion plans) and modest amenities. The 2.4 million annual visitors are stultifying Riomaggiore, Manarola, Corniglia, Vernazza, and Monterosso, which cumulatively support about 4,000 residents. The rugged hiking trails that connect the dots are heaving under the foot traffic. Several of the routes are temporarily closed, such as the main section of Riomaggiore to Manarola, and Manarola to Corniglia. The National Park of Cinque Terre occasionally issues warnings such as this one from April: “Because of the high number of visitors, access to the Monterosso-Vernazza (SVA) trail may be temporarily interrupted to avoid congestion. It is however advisable not to undertake the trail between noon and 3 p.m.” There has been some chatter about limiting the number of hikers on routes that charge a fee and updating the park’s app to include Cinque Terre pedestrian traffic reports.

Overlooked: Porto Venere

The Italian village near Cinque Terre shares its UNESCO designation with the five hamlets, but it is not a Cinque. It is, however, one of three towns that stands guard over the Gulf of Poets, a muse for many writers and painters. One natural landmark even bears the name of a famous British lord and poet: Byron’s Grotto. The train does not service Porto Venere, so most people arrive by ferry or car, which keeps the crowds at a minimum. Most of the dining, drinking and shopping is centered along the waterfront and on the pedestrian street, Via Capellini. If you’re lucky, you might spot an A-lister; Apple CEO Tim Cook and Steven Spielberg have vacationed here. Or maybe you will cross paths with the local celebrity, Tarantolino, Europe’s smallest gecko. The itty-bitty reptile lives in Porto Venere Regional Park, a protected area that covers more than 950 acres of land and sea, including Tino Island. The military base is only open for guided park tours and on Saint Venerio Feast Day (Sept. 13). The celebration honors the seventh-century hermit monk who protected the Gulf of La Spezia from a much different strain of invaders than today’s.
