Denny Creek to Hartenstein Lake

Named for turn of the century Buena Vista Lawyer, George K. Hartenstein, Hartenstein Lake sits in a high basin just below treeline. The hike to the lake climbs steadily and sometimes steeply through pine and aspen forests and small open meadows. The trail is a well-marked, rocky singletrack into the Collegiate Peaks Wilderness Area. The views are spectacular and the lake is pristine and serene. You’ll probably be the only one there.

Watch for mountain goats above the lake. They were transplanted to Cottonwood Pass in the 1940s from Washington’s Olympic Mountains and have since spread over Colorado’s central mountains.

Options
At the junction with trail #1451 (Mile 1.2), you can climb Mt. Yale (14,196 ft.) if you’re very fit and get started very early. Alternatively, go right at Mile 2.0 and hike up to Brown’s Pass and Kroenke Lake. These are all wonderful hikes.
