Yosemite’s Mirror Lake: Gaze Upon Half Dome’s Perfect Reflection
A trip to Yosemite National Park is not complete without a hike to Mirror Lake. This famous destination is not a true lake, but rather a vast, shallow seasonal pool in Tenaya Creek. Its existence is due to a natural rockfall that occurred centuries ago, creating a dam in the canyon.

The Famous Reflection and Seasonal Change
When the water is still, the pool lives up to its name. It perfectly reflects the giant granite walls surrounding it. You can see Half Dome rising on one side and North Dome on the other. You may also see the reflection of Mount Watkins and the Washington Column. This is a truly beautiful and classic Yosemite view.
The amount of water changes completely with the seasons. The pool gathers water behind the natural rock dam. Beyond the dam, Tenaya Creek rushes through several cascades and continues to flow. During a visit my family and I took in June 2017, the water flow was incredibly strong. It truly felt like a roaring river. However, by late summer and fall, the lake mainly dries out. When this happens, the area transforms into a beautiful open space called Mirror Meadow.
Easy Trail Access and The Full Loop
You can access Mirror Lake using two main options, both of which start at Shuttle Bus Stop #17. A nearby parking lot is also available for those driving their own cars.
The most popular option is a very easy, two-mile paved trail that runs round-trip to the lake. It starts on the north side and is often crowded. This route has a minimal elevation gain of about 100 feet. This paved path is suitable for bicycles, strollers, and leashed pets.
For a longer, more rewarding experience, consider hiking the full Mirror Lake Loop. The loop is about 4.5 to 5 miles long. It takes about two to three hours and also features minimal elevation gain. To start the scenic dirt portion, take the dirt road into the woods from the bus stop. Stay right when you reach the bridge. This scenic dirt path follows Tenaya Creek, providing ample shade. This trail is mostly level but does include some steeper, brief climbs.
When you reach the natural rock dam, you should stop. This spot is excellent for pictures. You can look upstream at the calm, mirror-like pool. Then look downstream at the powerful, gushing creek.
Once you pass this divide, you will see the full, stunning reflections of the cliffs and trees. We always stop here for a break, a picnic, and photos. Travel Tip: Vault toilets are available near the lake, but please note that there is no drinking water along the route.
The whole loop continues past the lake and eventually crosses two bridges before circling back along the paved north side. Be aware that the scenic south side trail can become very muddy or icy in the spring and winter due to its shaded nature.
You can also reach the lake by starting your walk near the Ahwahnee Hotel. This route leads you past the towering Royal Arches and below North Dome before connecting to the main trails.
