Lake Tahoe Tourist Guide, USA. Tour North Lake Tahoe, South Lake Tahoe. Whether you swim, fish, sail, or simply rest on its shores, you'll be wowed by the overwhelming beauty of Lake Tahoe, the largest alpine lake in North America. Famous for its cobalt-blue water and surrounding snowcapped peaks, Lake Tahoe straddles the state line between California and Nevada. The border gives this popular Sierra Nevada resort region a split personality. About half its visitors are intent on low-key sightseeing, hiking, camping, and boating. The rest head directly to the Nevada side, where bargain dining, big-name entertainment, and the lure of a jackpot draw them into the glittering casinos. To explore the lake area and get a feel for its many differing communities, drive the 72-mile road that follows the shore through wooded flatlands and past beaches, climbing to vistas on the rugged southwest side of the lake and passing through busy commercial developments and casinos on its northeastern and southeastern edges. Another option is to actually go out on the 22-mile-long, 12-mile-wide lake on a sightseeing cruise or kayaking trip.
