Mirror Lake and Mirror Meadow

Mirror Lake is the easiest way to stand directly beneath Half Dome, and one of the valley walks that is just as rewarding in winter as in spring. The trail starts at shuttle stop 17 in the far east of Yosemite Valley and follows Tenaya Creek into the narrow canyon between Half Dome and the cliffs below North Dome and Washington Column. The National Park Service describes it as an easy-to-moderate outing: about two miles round trip to the lake and back, with only around 100 feet of elevation gain, or a five-mile loop around the lake that takes two to three hours. The first mile follows a paved service road, which also makes it suitable for bikes, strollers and leashed pets on that section only; beyond it the trail becomes a dirt path. The lake itself is a lesson in change. It is a shallow pool on Tenaya Creek, fullest in spring and early summer when snowmelt fills it and on calm mornings mirrors Mount Watkins and the face of Half Dome; by late summer it often dries to a grassy flat that people call Mirror Meadow. Trailside exhibits explain how sediment is slowly filling the basin, turning lake into meadow, and touch on the cultural history of the area. In winter the canyon is shaded and cold, ice and snow often cover the south side of Tenaya Creek, and the quiet is remarkable — a fine short outing when higher trails are closed. There is no parking at the trailhead; park at Curry Village or elsewhere in the east valley and walk or ride the free shuttle. Vault toilets sit about half a mile in and at the lake, but there is no drinking water on the trail.

Why it is worth the walk. Most valley viewpoints show Half Dome from a distance; at Mirror Lake you are underneath it, looking up the sheer northwest face that climbers made famous, with Tenaya Canyon opening toward the high country beyond. The scale is humbling, and the changing lake — mirror, marsh or meadow depending on the month — gives repeat visitors a different scene every season. Photographers aim for calm spring mornings, when the reflection is at its best, and for clear winter days after snow, when the granite is etched in white.

Walking it well. Start early in spring and summer to beat the crowds and catch still water. In winter, wear boots with good grip or carry traction devices: the NPS warns that the south side of Tenaya Creek can be icy and slippery in winter and early spring. Stay on the trail and away from the creek banks, as crossings can become dangerous quickly when flows rise. For the full loop, allow two to three hours and continue past the lake up Tenaya Canyon before crossing back. Bring water and snacks, since none is available on the trail, and pack out everything you carry in.

Who it suits and what to pair. Families with young children can manage the paved first mile easily, and many turn around at the lake. Couples will enjoy the loop's quieter second half, and winter visitors get one of the most reliable snow-season walks in the valley. Pair it with lunch at Curry Village, an afternoon on the Valley Loop toward El Capitan, or an evening skate at the Curry Village ice rink.
