The Eastern Sierra is a dramatic transmountain region along US Route 395, straddling northern California and southern Nevada. It’s characterized by towering granite peaks — including Mount Whitney, the highest point in the contiguous US — deep glacial lakes, expansive high desert basins and iconic landmarks such as Mono Lake and Owens Lake. Visitors come for multi-day hikes in Bishop Pass, climbing on Yosemite National Park's eastern flanks, fishing and kayaking in remote lakes and winter recreation in higher elevations. The region is served by small gateway towns like Bishop, Mammoth Lakes and Reno, with extensive outdoor access, year-round weather extremes and a mix of public lands including parts of Inyo, Mono and Bishop Creek drainage basins.
