Rocky Mountain National Park, Colorado
Sky Pond Trail
A Glacier Gorge classic past Alberta Falls, The Loch, and Timberline Falls to a high lake beneath the Keyboard of the Winds. Snow often lingers into early summer.
Parking: Glacier Gorge and Bear Lake lots fill early. Use the park-and-ride and shuttle when it is operating.
Permits: Day hikes do not need a wilderness permit. Timed-entry vehicle reservations may still apply. Figures on this page are typical planning ranges, not a substitute for the park’s current trail report.
Overview
Sky Pond sits in a steep cirque in the Glacier Gorge area of Rocky Mountain National Park. The standard route starts at the Glacier Gorge Trailhead (or Bear Lake if that lot is the one you can actually park in) and climbs through spruce and fir to Alberta Falls, then to The Loch. Beyond The Loch, Timberline Falls is the crux for many hikers: a wet rock slab with a worn line that can hold ice. Glass Lake is the first tarn; Sky Pond is a short distance farther. This is a popular trail. Popularity does not make the slab trivial, and afternoon thunderstorms are a standard summer pattern in the Colorado Front Range.
Why Hike This Trail
- You want a single hike that stacks a waterfall, a forest lake, and an alpine tarn.
- You are steady on wet rock for a short scramble.
- You can start early enough to be below treeline before typical afternoon storms.
Route Description
- Confirm whether Glacier Gorge parking is using a timed-entry plus parking reservation system for your date. Many summer days require a park timed-entry permit. Check nps.gov/romo.
- From Glacier Gorge, follow signs toward Alberta Falls. The trail is rocky and often busy.
- Continue to The Loch. This is a reasonable turnaround if weather or fitness says so.
- The route to Timberline Falls steepens. The rock beside the falls is the usual scramble. It is not a technical climb, but it is exposed to a slip into water and rock.
- Glass Lake appears first. Sky Pond is the larger lake at the head of the gorge. Return the same way; the downclimb on wet rock is the slow part.
What to Expect
- Rocky trail surface that is hard on feet. Trail shoes with protection help.
- Snowfields into June or July in some years.
- Crowds at Alberta Falls; fewer people at Sky Pond, but not solitude on summer weekends.
- Wind at the lake even when the lower forest is calm.
Best Time to Visit
Mid-July through September is the most straightforward window for snow-free rock. September can bring quieter trails and earlier storms. Winter and spring travel here is a different skill set (ice, avalanche terrain awareness) and is not covered as a casual hike on this page.
What to Bring
- Layers, including a rain shell. Summer storms build fast.
- Water and a filter if you prefer not to carry all 9 miles of water.
- Microspikes in shoulder season if the slab is icy.
- Sun protection at elevation. The lake sits well above 10,000 feet.

How to Prepare
- Get cardiovascular work on hills. The mileage is moderate; the rock and altitude add effort.
- If you live at sea level, keep the first Front Range day easier than Sky Pond.
- Download the park map. Junctions around Loch Vale are signed but still missed when people follow crowds.
Nearby Attractions
- Emerald Lake from Bear Lake
- Nymph and Dream Lakes as shorter lake walks
- Trail Ridge Road viewpoints when the seasonal road is open
Nearby Places to Stay
- Estes Park is the main gateway town on the east side.
- Park campgrounds (Moraine Park, Glacier Basin) when open and reserved.
- Grand Lake for a west-side base if you are also driving Trail Ridge.
Frequently Asked Questions
Is the scramble required?
Reaching Sky Pond on the standard route means climbing the rock beside Timberline Falls. If that looks beyond your comfort, The Loch is still a full alpine-lake day.
Do I need a reservation?
Rocky Mountain National Park has used timed-entry reservations in peak months, sometimes with a separate Bear Lake corridor window. Check the official park site for the dates you are traveling. A reservation is not a parking guarantee.
Safety Notes
- Start early to reduce thunderstorm exposure above treeline.
- Do not stand on wet slabs to take photos of the falls.
- Altitude affects appetite, judgment, and recovery. Turn around if you feel unwell.
- Stay on trail to protect fragile tundra and avoid social paths around the lakes.
