Mirror Lake

Overview

Mirror Lake is a seasonal basin in the far end of the Valley, famous for glassy reflections of Half Dome and Mount Watkins when conditions are right. In drier months it shrinks into Mirror Meadow, trading reflections for wide sandbars and golden grasses. The spot sits in a glacially carved pocket; over time, Tenaya Creek has been slowly filling it with sediment.

Route options

• Out-and-back: About 2 miles round trip, roughly 100 feet of gain, on a paved approach. It’s family-friendly and the most popular way to see the lake.
• Full loop: About 5 miles following Tenaya Creek beyond the lake, crossing two bridges and returning on the opposite side of Tenaya Canyon. Quieter, with varied terrain and some rocky sections.
• Use only the signed bridges—don’t try to shortcut across Tenaya Creek.

Seasonality and water levels

• Spring to early summer: Best chance for a full lake and classic “mirror” photos, especially on calm mornings. High flows can be swift—treat moving water with respect.
• Late summer to fall: The basin often dries to meadow; expect sandbars and fall color instead of reflections.
• Winter: Open year-round with fewer people; the south side of the loop can be shady, slick, or icy—consider an out-and-back on the north side if conditions are dicey.

Best time to visit

• Aim for early morning in spring or early summer for the calmest water and strongest reflections.
• Start early to beat crowds and midday heat; late-day winds often ripple the surface.
• Autumn brings meadow scenes and quiet, but the “mirror” effect is unlikely.

Getting there

• Take the free Valley Shuttle to Stop 17 (Mirror Lake Trailhead). There’s no public parking at the trailhead; the closest options are around Curry Village or the Valley trailhead lot on Happy Isles Loop Road.
• Facilities: Vault toilets about 0.5 mile in and again near the lake. There’s no drinking water—bring your own.
• Bikes, strollers, and leashed pets are allowed on the paved first mile only; park bikes where pavement ends before continuing on foot.

Safety and etiquette

• Stay on the trail and use bridges—what looks ankle-deep can be pushy, cold water.
• In winter and early spring, expect ice on shaded sections; traction and caution help.
• Warm-season hikers often report mosquitoes; pack repellent and plenty of water.
• Pack out all trash; sandbars can make pleasant picnic spots when the lake is low.

Views and extras

• Expect big perspectives of Half Dome from near its base, Tenaya Canyon’s granite walls, Washington Column, and Mount Watkins. Keep an eye out for birds and butterflies, especially in fall.
• The Snow Creek Trail branches beyond the lake for a much steeper adventure, if you want to level up your day.
