Tiki Trail D.C., through Aug. 31

You shouldn't need an excuse to drink tiki cocktails all month, but here's a good one: Throughout August, eight D.C. cocktail bars, including Hogo, Archipelago and the Truxton Inn, are participating in D.C.'s first Tiki Trail bar crawl. Grab a passport from any participating location, and get stamps every time you order a tiki drink at a new spot. When you've visited all eight bars, you've earned free admission to a tiki-themed party on Sept. 3 — but you have to fill the passport before you find out where it is.  Cocktails $9-$13, depending on location.

Summer Evenings at the Hirshhorn, Every Thursday in August

If you've been meaning to get to the Hirshhorn to see Ai Weiwei's "Trace at Hirshhorn" or the "Masterworks From the Hirshhorn Collection," the museum is giving you five extra chances this month, staying open late every Thursday for pop-up events and tours. Highlights include curator-led tours of "Masterworks" on Aug. 31 — it closes a few days later — and a screening of the award-winning documentary "Ai Weiwei: Never Sorry" on Aug. 17. The museum will be open as usual each night, and the Tortoise and Hare Bar and Grille will run a pop-up bar. 5 to 8:30 p.m. Free.

BrickFair at the Dulles Expo Center, Aug. 5-6

From movies to architectural models, Lego is bigger than ever. The company's popularity is on display at the BrickFair, which fills 130,000 square feet with everything Lego: a 25-foot-long model of the battleship U.S.S. Missouri; the giant Rube Goldberg-esque Great Ball Contraption; even a Lego mini-golf course. (And yes, there are plenty of vendors selling rare and original sets, figurines and accessories for Lego fans of all ages.) Saturday from 10 a.m. to 5 p.m.; Sunday from 10 a.m. to 4 p.m. $17 in advance (includes expedited entrance and special Lego tile). $15 at the door. Children aged 3 and younger free.

Otakon at the Walter E. Washington Convention Center, Aug. 11-13

After 18 years in Baltimore, one of America's largest anime conventions is moving to D.C. It's Otakon, a celebration of Japanese culture, from anime and manga to arcade games, karaoke and cosplay. Expect Q&A panel sessions with anime directors and voice actors, free video game sessions, art displays, movie screenings, dance parties and costume contests over three packed days. $80-$95 in advance, $100 at the door.

3 Stars Brewing Fifth Anniversary, Aug. 12

The team at 3 Stars Brewing doesn't do anything halfway. At their fifth anniversary party, the upper Northwest brewery is unveiling four new beers, including collaborations with New York's Interboro and Long Island City Beer Project, a double IPA, and a barleywine made with Ohio maple syrup. That's just the beginning of the beer list, which co-founder Dave Coleman says will feature at least 30 taps, including selections for breweries that 3 Stars has previously collaborated with, such as Other Half, J. Wakefield and Graft Cider. Rappahannock Oysters are bringing oysters on the half-shell, Chiko is roasting a pig, Jerkface is making specialty jerky, and Ice Cream Jubilee provides frozen treats. Entertainment comes from DJs Smudge and Keenan Orr, and a performance by the School of Rock. 1 to 7 p.m. $20; $50 VIP includes admission at noon, additional drink tickets and a swag bag.

The Roots at MGM National Harbor, Aug. 13

Questlove and crew’s main gig these days may be as Jimmy Fallon’s official house band on “The Tonight Show,” but here’s a chance to catch them cutting loose in the fairly intimate MGM National Harbor theater. After all, their freewheeling live performances are what helped make the prolific hiphop group famous, as opposed to drum-offs with Justin Bieber on late-night television. 8 p.m. $63 to $314.

Metropolitan Washington Restaurant Week, Aug. 14-20

Excellent news for eggs Benedict fans: The $22 brunch option unveiled for winter Restaurant Week is back for summer. That’s in addition to the multicourse $22 lunch and $35 dinner deals on menus across the District, Maryland and Virginia. Make a reservation for your favorite spot or try something new: Veggie-focused Sally’s Middle Name, Mike Isabella’s new Moroccan spot Arroz and the Mosaic District’s pizza and pasta outpost of Alta Strada are participating for the first time. Available at more than 250 local restaurants. $22 to $35 per person, excluding tax and tip.

Shakespeare Theatre Free for All at Sidney Harman Hall, Aug. 15-27

Fun fact: This is the first time the Shakespeare Theatre Company has ever performed "Othello" as its annual free summer production. Faran Tahir features in the title role, as he did during the play's acclaimed 2016 run. There are two ways to get free tickets: Enter an online lottery the day before the performance you wish to attend, or wait in line outside the Penn Quarter theater for the roughly 200 seats given away two hours before showtime. (The line usually begins about two hours before the box office opens.) Tuesday and Wednesday at 7:30 p.m., Thursday and Friday at 8 p.m., Saturday at 2 and 8 p.m., Sunday at 2 and 7:30 p.m. Free.

Arlington County Fair, Aug. 16-20

We're in the midst of County Fair season, which is great news for fans of midway rides, demolition derbies and heavily caloric foods. But if you don't have a car, as is the case for a growing number of Washingtonians, it can be tough to get out to fairgrounds in Manassas or Gaithersburg. That's the advantage of the Arlington County Fair: It's completely Metro-accessible, thanks to shuttle buses running from the Ballston and Pentagon City Metro stations, making it easier to catch the racing piglets, bands and competitive vegetable exhibits. Wednesday and Thursday from 5 to 10 p.m. Friday from 2 to 11 p.m. Saturday from 10 a.m. to 11 p.m. Sunday from 11 a.m. to 10 p.m. Free.

DC Beer Week, Aug. 20-27

After moving to September in 2016, DC Beer Week has returned to its traditional late August place on the calendar. Most of the "marquee" events are back, including Brewers on the Block, a festival with more than 20 brewers outside Union Market on Aug. 20; DC Brau's all-you-can-eat crab feast at the Quarterdeck on Aug. 23; and the BrewHaHa at Old Ebbitt, which finds 10 breweries paired with 10 local chefs, on Aug. 26. Look for Solidarity: Brett IPA, a collaboration between D.C., Maryland and Virginia breweries, on tap throughout the week. Dates and times vary. See the DC Beer Week website for more details.

Solar Eclipse Viewing at the National Archives, Aug. 21

A solar eclipse is coming to America for the first time since 2012, and The National Archives is hosting a special viewing experience just for the occasion. In addition to viewing the eclipse safely through solar telescopes provided by the Air and Space Museum, visitors can explore the archives themselves and learn more about the history and facts surrounding past solar eclipses. There won’t be another eclipse viewable from the United States until 2024. 1 to 4 p.m. Free.

Comcast Xfinity Outdoor Film Festival at Strathmore, Aug. 24-26

Summer isn’t complete without an outdoor movie. Round up your family and a couple of blankets for a special viewing of Moana, Rogue One: A Star Wars Story, or The Lego Batman Movie on the lawn at Strathmore. The event is free, but there will be dinner available for purchase from Ridgewells summer grill. Proceeds from the event go to benefit NIH children’s charities. The gate opens at 7:30 and the movie begins as soon as the sun goes down. Don’t forget the bug spray! 7:30 p.m. Free.

National Park Service Birthday, Aug. 25

On August 25, 1916, President Woodrow Wilson signed an act creating the National Parks Service. It began as a collection of 35 sites, and in the last hundred years has grown into a vast system of 417. On August 25, celebrate the 101st birthday of the NPS by visiting any National Park for free. Luckily, the DMV area is home to many of these sites, so you won’t have to go far to take advantage of this opportunity. Visit and explore beautiful places like Great Falls Park, Harper's Ferry National Historic Park, or Prince William Forest Park. A full list of parks and information for visitors is available on the NPS website.

17th Street Festival, Aug. 26

The 17th Street Festival is often overshadowed by other urban street parties, but the eight-year-old festival, which takes over 17th Street NW between P and R streets, is a fun day out, with mariachi and marching bands, flamenco and Chinese dragon dancers, drag performances and a dog parade. Artists and vendors set up stands, selling paintings, jewelry and clothing. Kids play on a moon bounce and ball pit. Admission is free, but organizers sell a $10 ticket that provides food and drink discounts at restaurants and bars up and down the street. (Unlike other block parties, the 17th Street Festival doesn't have vendors in the middle of the street.) Noon to 6 p.m. Free.
