10 scenic spots to swim, float, and soak in the sun at the West's amazing national parks
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.
