Welcome to the Lake Tahoe Open Water Swim. Lake Tahoe is one of the world’s most famous sporting playgrounds. The region has an almost endless variety of spectacular mountain biking trails, adventurous hikes and, of course, waterborne activities on the “Big Blue” - Lake Tahoe - one of the largest, deepest and purest alpine lakes on earth. The Lake Tahoe Open Water Swim is a celebration of the natural environment of the Tahoe region featuring the beautiful, clear and clean water of Lake Tahoe and the white sand beaches of California's Sugar Pine State Park. There is a 1/2 mile, 1-mile, and 2-mile course set up just off the beach of the scenic Ehrman Mansion where spectators can see the action first hand from the expansive pier.
