Mirror Lake

Mirror Lake is a small, seasonal lake on Tenaya Creek between North Dome and Half Dome in Tenaya Canyon. It is the last remnant of a larger glacial lake that once filled most of Yosemite Valley and is slowly disappearing due to sediment accumulation. It is fullest in spring and early summer when Tenaya Creek carries fresh snowmelt. Mirror Lake got its name from stunning reflections of the surrounding cliffs on windless days. Sings along the trail describe the lake's transformation from a lake to a meadow and the area's cultural history. By late summer, the lake is often referred to as Mirror Meadow due to water dispersing and it becoming a grassy and sandy area. Hikers should be cautious of slick conditions along the south side of the loop trail during winter and early spring.
