This feature-filled hike rises moderately past Alberta Falls to Mills Lake and Jewel Lake, then grows steep and rugged to Ribbon Falls on the final push to Black Lake:

The Loch Vale Trail rises steadily through young aspen and mixed pine to Alberta Falls (.85 miles : 9,423').

It continues to the North Longs Peak Trail split (1.6 miles : 9,768'), banks SW and flattens through a slot between Thatchtop Mountain (12,668') and the Glacier Knobs to Glacier Junction (2.1 miles : 9,804'). Turn left for Mills Lake on the Glacier Gorge Trail.

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.

Worth Noting

  • 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.

"A different experience than my hike back in March. Very little snow on the trail all the way up to Jewel Lake. After Jewel the trail would have areas covered in snow, and the last mile or so was mostly covered. The snow was slushy and icy. Traction device and walking stick a big help. There were a couple places where you had to climb to get to trail. The creek is running fast from Black Lake all the way down to Jewel. Be careful with the slippery snow. Before I put traction device on I did lose footing and slid about 20 ft down toward creek before stopping about 7 or so ft shy. Trail after Jewel was hard to follow, but good thing with this hike ( and with snow still being on ground) is that you point your way up glacier gorge and you will eventually find the trail again."

"Beautiful and challenging winter snow-shoe hike. A little trouble picking up the trail after leaving Jewel Lake due to several different paths heading out. But take the hint and just keep heading down the creek you will pick up the trail. Worth the effort. When you get to Black Lake, head to Western edge and you might catch some rock/ice climbers on the far end walls."

"This remains one of the best hikes on the front side of the park. Above Jewel Lake is s stretch of about 1/2 mile with scores of downed trees - in some places more downed than standing - the result of a fall 2011 windstorm. The trail is now 100% passable, and I offer a huge THANK YOU to the trail crews that went in and cleared the downfall. "

"Would like to secure tent site for the nights of 9/5 & 9/6 for the Glacier Gorge trail below Black Lake and Spearhead. Dan"
