The largest alpine lake in North America, Lake Tahoe is a cobalt blue lake atop the Sierra Nevada mountain range. On its eastern shores, gently sloping beaches, crystal-clear water and interesting rock formations allow for wonderfully sublime swimming, kayaking and scuba diving at Sand Harbor. Boaters, water-skiers and fisherman can easily launch from one of the park’s two ramps. Visitors who would like a peaceful retreat from surf and sun can picnic in the shade of cedars and Jeffrey pines in one of many picnic sites equipped with barbecues and tables.
