very pretty lake. there is a bridge out and trails are not clearly marked. the water is beautiful and you should be able to see a couple other lakes on the way as well

The trail was nicely maintained and has had some recent work.
The horses were sad to see yellow jackets about 3/4 of way to top.
On horseback the trail is a challenge best for experienced trail riders.

The trail started (for us) at the Green Lake Trailhead. A few miles of relatively flat walking til we hit the second green lake. the bridge was out there so we went over the logs that had fallen to cross the water. Once on the other side, the ascension starts. Walking for a little while, you hit the "y" in the road that takes you to (left) echo lake and (right) lost lake. We took the right and it's a pretty steady uphill hike. It was snowing and everything was white and beautiful. Finally arriving at the lake on the left, we noticed that it was hidden with no signage whatsoever. Thank goodness for the steps in the snow so we could follow. Overall, it was a majestic little lake that was a brilliant bluish green. Very peaceful and st this tone
