BLOCK ISLAND, RHODE ISLAND
This hideaway just off the coast of Rhode Island has miles of unspoiled beaches and offers a break from the hectic pace of everyday life. "It's a great place for families," says Mary Hickey, special projects editor. "I highly recommend renting bicycles with a tagalong or baby seat, and touring the island that way." Be sure to check out the historic lighthouses, old Victorian hotels, Sachem Pond Wildlife Refuge, and the Mohegan Bluffs, which overlook the ocean. At the end of a bike ride or a day at the beach, stop by the Ice Cream Place (401-466-2145) to cool off.
Set on Cape Cod's bay side, Brewster is a haven for families. During low tide, kids have a blast exploring the Brewster flats, where the bay recedes more than a mile, trapping little sea creatures in tidal pools. For freshwater fun, families head to Nickerson State Park and swim in its sandy-bottomed kettle ponds. Afterward, kids often clamor to stop at the Brewster Store (www.brewsterstore.com) for its impressive array of penny candy. Not surprisingly, the town also features great seafood. "We love going to Kate's (508-896-9517) for their fried clams and ice cream," says Linda Fears, deputy editor.
BUCKS COUNTY, PENNSYLVANIA
For children, the highlight of a visit to Bucks County is undoubtedly Sesame Place (215-752-7070, www.sesameplace.com).

For a different kind of fun, visit Washington Crossing Historic Park (215-493-4076) to see where George Washington's army crossed the Delaware. Or take your kids tubing or rafting along a shallow, gentle stretch of the river just north of New Hope (215-297-5000, www.rivercountry.net). "There's even a hot-dog stand on a little island where you can eat, hang your feet in the water, and watch people float by," says Diane Debrovner, senior editor.
Mid-Atlantic & South

And don't pass up the National Museum of American History (202-357-2700, www.americanhistory.si.edu). "There's no way to describe this magical place adequately," says Bruce L. Flamm, M.D., a Parents adviser. "There's even a full-size locomotive on display on the first floor."
ASHEVILLE, NORTH CAROLINA
Could a city that boasts a highway as one of its top attractions be worth a visit? If it's Asheville, North Carolina, the answer is yes. The Blue Ridge Parkway, which winds through the Blue Ridge Mountains, has some of the most breathtaking vistas in the country. "The views are absolutely gorgeous," says contributor Emily Abedon. Along the way, you can access plenty of great hiking trails -- or you can opt to head directly to Sliding Rock, a natural 60-foot water slide that's a favorite with families. For indoor fun, Abedon suggests trying the Health Adventure at Pack Place (828-254-6373, www.health-adventure.com), a children's discovery center.
HILTON HEAD ISLAND, SOUTH CAROLINA

Stop by the Coastal Discovery Museum (843-689-6767, www.coastaldiscovery.org) for hands-on exhibits about the island's environment and heritage.

A trip to Hilton Head can also be relaxing for parents who golf -- the island has more than 20 courses.
Nestled in the North Georgia Mountains, Helen captures the look and feel of a Bavarian village. On Main Street, shopkeepers dressed in lederhosen welcome visitors to their quaint stores, and restaurants offer a unique mix of European and Southern cuisine. "We'd stay at the Castle Inn (877-878-3140, www.castleinn-helen.com), which is a treat for kids because the outside really looks like a castle, and the rooms have beautiful views," says Kourtney Eidam, assistant editor. Fun family activities nearby include panning for gold, tubing down the Chattahoochee River, and taking the easy hike to breathtaking Anna Ruby Falls.
THE FLORIDA KEYS
Getting to the Keys is half the fun. With the ocean on both sides, the Overseas Highway has sweeping views of the Atlantic and its coral islets. "We love the Keys," says Parents adviser Michael Thompson, Ph.D. "They're funky, simple, and relatively inexpensive."

The living is easy in Grand Haven, on the eastern shore of Lake Michigan. Picture sandy beaches, mild waves, colorful sailboats on the horizon, and strolls along the 2 1/2-mile boardwalk. Off the shore, delight your children with a trolley ride (616-842-3200). Head back to the harbor for the sunset spectacle of the world's largest musical fountain. Oh, and don't forget the blueberries. They're a star attraction -- there's even a shop dedicated to them in nearby South Haven (877-654-2400). "I came to Grand Haven as a child, and I still remember the blueberry pies brimming with fruit," says Maura Christopher, senior editor.
All the city's a stage in Branson. On any given day, this high-energy Ozark resort town offers scores of toe-tapping shows for families -- from country music to variety acts.

And Silver Dollar City, a 61-acre theme park (800-475-9370, www.silverdollarcity.com), is a "don't miss," says Heather Gowen, senior news editor.

Just southwest of Branson, overlooking scenic Table Rock Lake, is the Ozark Mountain Resort (866-804-8444, www.omrcondo.com), great for fishing, swimming, and carefree fun.
LONG BEACH PENINSULA, WASHINGTON
A beachcomber's paradise, the peninsula has one of the world's longest stretches of sand -- 28 miles unobstructed by beachside condos and hotels. While few visitors swim in the rough, often frigid water, kids love to splash through the puddles, dig for clams, build sand castles, and explore the tidal pools. Families can trace the final stage of Lewis and Clark's epic expedition at the Lewis & Clark Interpretive Center (360-642-3029), in Fort Canby State Park, or tour the unique World Kite Museum (360-642-4020, www.worldkitemuseum.com).

From its spectacular waterfalls to its ancient giant sequoias, Yosemite National Park will amaze your children at every turn. "I was really struck by the park's magnificence," says designer Stephen Christensen. "El Capitan, in particular, was awe-inspiring." More than 3,000 feet high, El Capitan is the largest hunk of granite on the planet, and its sheer face is often dotted with expert climbers. Glacier Point, with its sweeping views, is another Yosemite wonder. In the valley just below Glacier Point is Curry Village (559-252-4848), which has moderately priced cabins, motel-style rooms, and a tented camp.

The cobblestone paths, on the banks of the San Antonio River, wind among gardens, shops, and restaurants. "The food is amazing in San Antonio," says Robin Immerman, beauty editor. "I was hooked on the corn fritters."

Beyond the U.S.
Little islands, mountains, a rain forest, and a pristine city -- Vancouver, in British Columbia, Canada, has something for everyone. The city's Stanley Park (604-257-8400, www.parks.vancouver.bc.ca) is a great first stop. "We rented tandem bikes and had the best time," says Stacey Felsen, a Parents contributor. The park is also home to the Vancouver Aquarium and the Children's Farmyard. To see the city from a different perspective -- 3,700 feet up, that is -- jump on the Grouse Mountain Skyride (604-980-9311, www.grousemtn.com). For a fun time shopping, take the speedy water bus to Granville Island, where a kids' market (604-689-8447, www.kidsmarket.ca) caters to the allowance set.
THE ATLANTIC OCEAN
Looking for a voyage rather than a destination? A Cunard cruise (www.cunard.com) on the Queen Elizabeth 2 -- or, starting in 2004, the Queen Mary 2 -- offers an unbeatable way to experience the Atlantic: by sailing from New York to England. "I love the annual Family Cruise," says Sally Lee, editor-in-chief. "It's such a relaxing experience, and if you choose the right cabin -- think the inside, lower decks -- and bunk with the kids, the trip is affordable." On board, there's a video arcade, a computer learning center, planned children's activities, and plenty more. And the caregivers at the children's center are all trained nannies. "We visited the casino, health spa, and pools, and we could really relax, knowing our children were in good hands."
