Timberline Falls is a cascade waterfall in Colorado.

Timberline Falls sits on Icy Brook. You'll find it in Larimer, Colorado. It is protected within Rocky Mountain National Park (NPS).

This is a backcountry waterfall: a remote, long, or permit-required trek for prepared visitors. The walk to the main viewpoint runs about 9.5 miles round trip. Base a visit out of Estes Park, the closest town.

When to go: Summer (June-September). Like most waterfalls, Timberline Falls runs highest after snowmelt or heavy rain and can thin out in late summer, so it's worth checking recent streamflow and the land manager's conditions page before a long drive.
