Boulder, CO: Long Lake Loop

Boulder, CO: Long Lake Loop

Enjoy the views and high elevation while looping around Long Lake in the Indian Peaks Wilderness.

Heading out the door? Read this article on the new Outside+ app available now on iOS devices for members! Download the app.

Hike counterclockwise around Long Lake to get the elevation gain out of the way early on and save the best views for last. The trail is through the trees most of the way around and then opens up to see the Indian Peaks back in the distance. Even the drive to this trailhead is beautiful.
