I arrived at the trailhead early in the afternoon. My initial plan was to hike Lake Dorothy, but after having some issues with my car, I decided to go to Lake Serene instead. I was the only one on this hike and saw no one during the whole trip. During the first mile, you pass birch trees and do not have much cover from the sky. Early on, there is a sink hole in the middle of the trail, but you can walk around it. At 1 1/2 miles you have the option to hike to Bridal Veil Falls or continue to Lake Serene. There's no reason why you can't do both. It's only a 1/2 mile to the Falls. The trail to the falls is in great condition. At the fork in the trail, it's 2 miles to Lake Serene. Except for the first 1/4 mile, or so, you climb continuously to the lake. The trail is rocky with many stairways along the way. Snow made its appearance during the last 1/3 mile. The snow was about 2 - 4 inches deep. When off the trail, at the lake, the snow was about 8"" deep. While at the lake, it was extremely windy. The lake is about 99% frozen. There was a lot of snow sliding off Mt Index. It began raining while I was sitting at the lake. I was surprised to find litter on the trail. There wasn't much, but finding any trash is disappointing. I picked up what I could see, then hiked it out. In total, there were two blow-downs, but you can easily navigate over or around them. There is much to see on this hike, an alpine lake, a couple of water falls, you cross over the creek a few times, Mt. Index, the valley below, numberous birds and deer.
