Black Lake - 9.6 Miles Round-Trip
Black Lake is located 4.8 miles from the Glacier Gorge Trailhead in Rocky Mountain National Park. It fills a deep cirque at treeline carved from the base of McHenrys Peak, The Arrowhead, Chiefs Head Peak, and The Spearhead. This rugged trail leads deep into a spectacular glacial valley with access to Mills Lake, Jewel Lake and Ribbon Falls along the way:
A moderate climb continues to the North Longs Peak Trail split (1.6 miles : 9,768'), where it banks SW and flattens through a narrow gorge between Thatchtop Mountain (12,668') and the Glacier Knobs. The trail drops to Glacier Junction and bears left to Mills Lake (2.1 miles : 9,804').
The trail turns south across Glacier Creek twice and sections of cairn-marked rock slabs to Mills Lake (2.65 miles : 9,955'). Here you'll enjoy terrific views up Glacier Gorge and of the jagged ridges and peaks that define it.
The trail - now intermittently rugged, undulating and heavily rooted - follows the lake's east shore to its marshy juxtaposition with Jewel Lake (3.1 miles : 9,967').
It continues past Jewel Lake through a string of marshes aided by narrow, elevated planks. A cluttered forest reclaims the trail (3.2 miles), which closely follows Glacier Creek all the way to Black Lake. Anticipate steep undulations and occasional loss of clarity over the next 1.5 miles; when in doubt, simply hold your line and follow the creek.
You'll pass the Glacier Gorge Backcountry Campsite spur (3.35 miles : 10,068') and scale newly built stairs. Travel intensifies in a thick forest to a cairn-marked rock slab (3.85 miles : 10,205'), then moderates across a meadow with good views of the upper gorge (4.1 miles).
The Arrowhead (12,387'), Powell Peak (13,208) and McHenrys Peak (13,327') frame the west, and Pagoda Mountain (13,497') and Keyboard of the Winds - a line of pinnacles near the summit of Longs Peak - rise to the east. Chiefs Head Peak (13,579') and The Spearhead (12,575') cap the headwall.
Uneven travel continues up to Ribbon Falls (4.7 miles : 10,540'), which spill from the lip of Black Lake. The trail twists steeply beside the falls and hops a line of flat boulders across the outlet to Black Lake (4.8 miles : 10,630').
It scales a small knoll to the east shore (4.85 miles), where the remaining maintained portion turns sharply east and climbs above the lake along its main inlet. The trail gradually fades in high alpine benches, where unmaintained routes branch off to Blue Lake, Green Lake and Frozen Lake.

- Arrive early to secure parking, avoid crowds and afternoon storms. Be mindful of changing weather and get below treeline before storms develop. Note that the gorge's high walls can block your view of approaching weather from the south and west.
- Jewel Lake's attractive shoreline - especially the west side - affords comparable views but appreciably more solitude than Mills Lake.
- Snow may linger on the trail well into summer; be patient with route finding and plan travel time accordingly.
Camping and Backpacking Information
Glacier Gorge Backcountry Campsite
- There is one designated site located across Glacier Creek in a heavily forested area. A sign 3.35 miles from the Glacier Gorge Trailhead leads over the creek on a footbridge to the site.
- Use red arrowheads on trees for additional guidance. Camp safely away from dead trees, as close as possible to the silver metal arrowhead.
Rules and Regulations
- Horses are not permitted beyond Glacier Junction (2.1 miles). There is a hitchrack located just beyond this junction where you may dismount.
Directions to Trailhead
Just beyond the Beaver Meadows entrance station, turn left onto Bear Lake Road. The Glacier Gorge Trailhead is located on the left side of the road and has limited parking. Additional parking and alternative access can be found at the Bear Lake Trailhead. This will add an additional 1 mile roundtrip to the hike.
