Trail guide
Sky Pond is a high-altitude out-and-back from Glacier Gorge Junction Trailhead to a lake beneath the Cathedral Spires. It passes Alberta Falls and The Loch, climbs beside Timberline Falls, crosses Lake of Glass, then reaches Sky Pond in a mountain cirque. Plan on about 9 miles round trip and roughly 7 hours. No standard full-route time was established, so treat that as a planning estimate. The trailhead is around 9,240 feet and Sky Pond is near 10,900 feet; the hard upper section includes a steep hands-on scramble.
Cross Chaos Creek and follow the Glacier Creek route toward Alberta Falls. At the early fork, stay on the Sky Pond line rather than turning toward Bear Lake. Around 1.6 miles in, turn right at North Longs Peak, then continue straight at Mills Junction onto Loch Vale Trail. At the Andrews Glacier split above The Loch, take the left branch toward Timberline Falls; Andrews Glacier is a separate route.
The approach climbs in short switchbacks beside Icy Brook before opening at The Loch, about 2.8 miles from the start. Read the signed junctions carefully: several nearby branches lead to different lakes and climbs.
Alberta Falls is roughly 0.8 mile in, a narrow cascade about 30 feet high in the Glacier Creek gorge. It takes its name from Alberta Sprague, part of an early Estes Park family. It is a good first pause, but only the beginning of the climb.
The Loch sits in a broad valley beneath Taylor Peak, Thatchtop and Sharkstooth. A switchback on the steeper approach gives a view of another waterfall on Icy Brook. The lake is also a long-running watershed monitoring site: researchers have tracked what wind and precipitation bring into this high basin for more than forty years.
A short distance beyond the Andrews Glacier junction, Timberline Falls comes into view. Rocky steps climb about 200 feet over roughly 0.15 mile to the base of its main drop, about 100 feet high. The route then climbs a steep chute beside the falls. Expect to use hands and feet over about 100 feet of rough ground; the first 30 feet are steepest.
Water can cross the rock, making the scramble slippery. Judge the surface before committing, and do not force it when wet, icy or snow-covered. You descend the same chute on the return, which can feel harder than climbing it. If this section is beyond your comfort, turn around before starting up instead of counting on an easy way around.
Lake of Glass, also called Glass Lake, lies just above the scramble. Its west shore is rugged, with rocky and sometimes faint tread. A moraine closes the upper basin. Continue carefully to Sky Pond, where cliffs enclose three sides of the water and the granite Sharkstooth spires rise above the shore. Taylor Peak sits across the lake and Powell Peak frames the southern side.
For a photo, include rocky shoreline in the foreground with the spires behind it; that gives the lake a sense of scale. The open water and exposed granite feel far removed from the forest below.
Start at Glacier Gorge Junction Trailhead on Bear Lake Road. The seasonal shuttle serves Glacier Gorge; starting at Bear Lake Trailhead adds about 0.2 mile round trip. Parking pressure on Bear Lake Road recurs, so check current park access and shuttle information before choosing a start. Carry food and water for a full day; no refill point was verified on this route. An early start helps leave time for the high elevation and exposed climb, especially when afternoon storms are possible.
Rocky Mountain National Park does not allow pets on its trails; service animals follow park rules. Published full-route distances vary: one measurement is about 9 miles round trip, while an older park table gives 4.9 miles one way, or about 9.8 round trip. The 2.4-mile out-and-back from The Loch describes only the upper segment, not this full hike.
