Mono Lake lies in the Great Basin on the outskirts of Yosemite National Park. There is no outlet around the lake, which makes this an alkali rich lake. Because the lake is high in dissolved salts, carbonate minerals precipitate and form along the shores. These castle like features are known as tufa. Beyond the tufa and to the west, you'll find views of Yosemite's peaks towering above as you paddle around the lake. Strong prevailing afternoon winds develop, making the waters rough and choppy. Try this paddle trip in the early morning when conditions are calmer. In addition to launching from Navy Beach, there is a boat launch site at Lee Vining Creek. Between April 1st and August 1st the area around the islands is closed off to protect the nesting of California gulls. Access to and camping on the islands are permitted all other months; contact Mono Basin National Forest Scenic Area for further information.
