Lounging motionless on the beach from sun up to sundown went out with the Bain de Soleil tan. Sure, you can swim -- but how many ocean laps can you really do? And you can read -- ho hum, another bodice is ripped. And sleep. And burn.

But for travelers who get antsy on the sand, there's an alternative: a bike and ferry tour of Long Island's eastern tip and Block Island.

The open-air trip is like a seashore sampler of Connecticut, Long Island and Rhode Island. Aboard any of the five ferries that connect these destinations you can see lighthouses from a captain's perspective and watch ospreys and seagulls soar in mixed company. While cycling between the ferry terminals, you can stop for juicy strawberries from a roadside farm stand, or tour a vineyard, or take a five-minute beach break -- before getting back to the real activity of biking and boating.

Our suggested three-night itinerary starts in New London, Conn., on the hulking Cross Sound ferry, which sails to Orient Point, N.Y. Now the biking begins: 10, 20, 30 miles (or less) a day. The little-trafficked Route 25 of Long Island's North Fork passes farm stands heaped with supersize produce, nubby pastures and pebbly beaches with views of Shelter Island, the first overnight stop. You can spend one evening here, or more. There's no rush to leave -- the ferries run often.

The commuter ferry to Shelter Island leaves from Greenport, an easygoing town with a carousel, a tall ship, a winery and an ocean's worth of seafood restaurants. The ferry to the island's north point takes no more than five minutes, and you'll want to ride it again and again. When you disembark, you'll find an island full of flowers and sailboats and homes you'll envy. The ferry the next day departs from the south end of Shelter Island and lands in North Haven, the jumping-off point for the South Fork portion.

This bike route is busier traffic-wise and has more towns to explore: Sag Harbor (great for whaling history buffs), East Hampton (for Pollock and Polo), Amagansett (for dosas as long as sticks) and finally Montauk -- where you can spend the second night in a classic beach motel or a fancier resort with a spa. The Montauk Point Lighthouse offers views of the last destination, the pork chop-shape Block Island, accessible by ferry from the Montauk Dock.

Before you return to New London, fill your hours on Block Island cycling from lighthouse to lighthouse, or beach to beach, or bar to bar. At the National Hotel's porch, order a frozen mud slide and wait for the ferry to chug into port.

Then watch the ferry leave -- without you. There will be another one tomorrow, and there'll be space for you on it. Summer, though, is less forgiving.
