Watanga Lake - 8.6 Miles Round-Trip

Watanga Lake (10,772') is located 4.3 miles from Roaring Fork Trailhead on the west side of the Indian Peaks Wilderness. The lake is fairly small but set among broad, flat meadows that give it a larger and particularly spacious feel.

The Roaring Fork Trail climbs steeply in the first mile, then moderates along the creek to the Watanga Lake - Stone Lake split.

The Watanga Lake Trail turns north and climbs 965' in 1.65 miles through an attractive subalpine forest to the lake. Several large ponds and meadows can be found just above the lake and are fun to explore:

The trail runs level around Pete’s Cove to the IPW Boundary (.18 miles), past which it climbs 810’ in just .8 miles to a bridge across the Roaring Fork (1.0 miles : 9,172’). Enjoy views over Granby and a bumper crop of thimbleberries on this challenging segment.

Travel eases up the north side of the creek in a progressively healthier forest (1.5 miles : 9,295’). It rises in short spurts to bridges at 2.35 miles and 2.58 miles into a brushy clearing at the Watanga Lake Trail split (2.65 miles : 9,805’). A number of campsites can be found in this wide, level area.

The Watanga Lake Trail arcs north and hops a creek to a new log bridge (2.9 miles : 9,860'), then forks right to hop the creek again (2.95 miles). This crossing can be deep / swift during peak runoff.

Grades steepen to another creek-hop (3.2 miles : 10,060') and into a thinning forest with good views south of Mount Irving Hale. You'll get a good sense of the challenging climb to Stone Lake from these points.

The trail dips to and crosses a creek (3.5 miles : 10,315'), then skirts a large meadow into a mature spruce-fir forest. Large, well-spaced trees with verdant ground cover and braided streams distinguish this attractive segment. Expect some tedious deadfall.

The trail turns sharply up the right side of the drainage (3.95 miles : 10,590') and switchbacks to a crest, from which it drops gently to Watanga Lake (4.3 miles : 10,772').

The lake entry point may hold snow well into July and can be a little tricky to maneuver out of. Head counter-clockwise to reach outlying meadows and ponds, and climbing routes to Watanga Mountain (12,375') on the Indian Peaks - Rocky Mountain National Park Boundary.
