Who said you need an ocean to go surfing? The 43-mile-long Lake Pend Oreille in Sandpoint, ID, has become popular for wakesurfing -- the watersport where you ride the crest created behind a motorboat. Here you can practice your moves from morning to night while taking in the scenery from 3 surrounding mountain ranges. When you’re finished, relax on one of the lake’s sandy beaches. The best part? No need to worry about sharks.
