Snow blanketed the valley on this cloudy but rain/snow-free winter's day. I decided to leave the snow shoes back at the cabin because I figured the trail would be well-packed, and it was. We saw lots of other people on the trail, and most of them just wore boots or even tennis shoes, although there were a few with cross-country skies and some with snowshoes. While the main trail was stamped down, using snowshoes would allow for exploration further afield.

Start of the trail to Mirror Lake

The trail leaves the shuttle bus stop and heads directly into the conifer forest. It's pretty much pancake flat up to and a little beyond the Tenaya Creek bridge. From the bridge, of course, we could see Tenaya Creek below. The trail then basically follows the creek upstream, with the creek on the right side of the trail.

After the bridge, there's a sign saying 0.6 miles to go to the lake. Shortly after that there's a sign saying that rented bikes are prohibited from going further, and to park your bike there (there's a rack). From then on, the trail starts to climb a bit, though the total elevation for the hike is only 180 feet, so it's never very steep.

The nice thing about hiking in the snow with kids is that it provides endless opportunities for them to play in the snow along the way to keep them occupied. They can write in the snow, have snowball fights, or make snow angels. The downside is that they'll probably expend more energy doing all this and may get tired hiking quicker.

Eventually we reached the lake, where there's a restroom and a sign saying that no bikes at all (or dogs) are permitted any further. The trail then basically continues along the shore of what's left of Mirror Lake. In summer, the lake pretty much dries up, although it didn't use to be that way years ago. The lake is now really a seasonal pool and recedes to display a meadow in summer. Interestingly, my family visited Mirror Lake two years before I was born, in the summer, and it was definitely a lake back then.

On this winter's day, Mirror Lake looked nothing like it did back then. For one, what we could see of the lake was frozen over. And of course there was snow on all sides. Because of that we could not see the iconic reflection of Half Dome in the surface of the lake. But we could still see Half Dome rising abruptly in front of us.

We settled down amongst the trees next to the lake and had a picnic lunch. While we did so, a family around the corner was making an igloo of sorts -- it sort of looked like a snow closet, about 6 feet high and big enough to fit 3 or 4 people packed in tightly. They probably spent about an hour on it before taking pictures and then leaving it there.

Half Dome

While taking pictures of the area I heard what sounded like the distant crackle of thunder. I looked up and saw a puff of white high up on the steep granite slopes. Apparently some combination of snow and ice had broken free and fallen in a mini-avalanche. This was quite common, as I heard this happen several times. I waited and tried to get a picture, but it was too hard to associate the sound with the actual place of the snow/ice fall. It was kind of soothing sitting there listening to it, though.

You could continue to take the trail around the lake, but we turned around and headed back the way we came. Supposedly the lake is 1.0 mile from the trailhead, but according to the GPS, it's only about 0.8 miles.

Back to trip report.
