The region has its plush side—just sample the Citron cocktail at sunset at Sardine Lake Resort—but its true heart is easygoing, low-key, and thrifty. There are more than 10 public campgrounds, including Sardine Campground, where every site has a view of the jagged Sierra Buttes. You can rent boats at Sardine Lake Resort. Or hit the area’s dozens of trails: Families can wander the easy 0.5-mile path to Frazier Falls; intrepid hikers can climb about 2.5 miles to the top of Mt.

From $187 U.S./person plus $425 U.S./vehicle; bcferries.com Surfing: Waikiki, HI When it comes to surfer snob appeal, Waikiki sucks. The Kelly Slaters, the Alana Blanchards, they’re shredding monster waves in Bali, Tahiti, across Oahu on the North Shore. But for beginners? Waikiki is utter bliss. Start with the water, a caressing 72°. Add a break that generates the world’s most gentle, evenly spaced 3- to 6-foot swells. Finally, note the wealth of instructors. We’re in awe of Hans Hedemann for a boardside manner that makes the far-fetched (you, standing up on a surfboard) seem easy. Here, you will ride a wave, and if Kelly and Alana aren’t shredding beside you, you’ll be having too much fun to care.

More: Explore Catalina Kayaking: San Juan Islands, WA It’s easy to be dazzled by talk of spotting breaching orcas, playful harbor seals, and colorful seastars. But once you’re bobbing serenely in 3-inch wavelets in the San Juan archipelago, you’ll understand the deeper seduction: the kayaking life, in which you’re no mere observer of the weather, the tides, and the marine life but a full participant among them. And there is just no better place to spend the night than camping on these serene islands. You might hear the distant thrum of boats on the water, but you’re in a different universe—one where your itinerary is shaped by nature. Anacortes Kayak Tours: 2- to 5-day tours $349–$849 May–Sep, including meals and gear; anacorteskayaktours.com Motorboating: Lake Powell, AZ A blue mirage set in red rocks, Lake Powell—which forms the watery heart of Glen Canyon National Rec Area—has nearly 2,000 miles of shoreline, which means a lot of Lake Powell beaches to choose from. A few, like Lone Rock Beach, can be reached by car. But some of the best are nameless coves accessed only by boat. Good thing you can rent powerboats at three lake marinas: Antelope, Bullfrog, and Wahweap. (Houseboats are also popular, but you can’t navigate into narrow coves as well.) Don’t miss a cruise to the lake’s south shore and Rainbow Bridge National Monument, home to the world’s largest known natural rock bridge. $15 per vehicle; nps.gov/glca or lakepowell.com (boat rental). Scenic floating: Yosemite National Park, CA With El Capitan and Half Dome towering above, the Merced River beaches in Yosemite Valley sometimes get forgotten.

Rent a four- to six-person raft at Curry Village Recreation Center, and float 3 miles to Sentinel Beach; the $26 fee includes shuttle service back to your start. In summer, take the El Capitan Shuttle to stop E4 and walk 1/4 mile to Cathedral Beach, or get off at E5, 1/2 mile from Sentinel Beach; $20 per vehicle; nps.gov/yose or 209/372-8319 (raft rental).
