Long Gulch Lake is one of the easier hikes in the Alps. Though it is a longer hike than its counterpart "Trail Gulch Lake" it's a little more mellow and far more scenic.
Along the way you will pass many meadows and lush fern forest, even a few mountain ponds.
You can do a loop over to Trail Gulch Lake, but the trail is hard to follow and not maintained.
If you like the idea of obscure trails and forgotten places, be sure to check out Saloon Creek and the Forks of Coffee Creek.
