Lake of Glass

Lake of Glass is one of Rocky Mountain National Park's most breathtaking alpine destinations, perched high in Larimer County along the famous Sky Pond trail. With a 4.7-star rating from visitors, this pristine lake lives up to its name with mirror-still waters that reflect the surrounding peaks in stunning clarity. Whether you are an experienced hiker chasing panoramic mountain views or a first-timer looking for one of Colorado's most memorable trails, Lake of Glass rewards every step of the climb.

The hike to Lake of Glass follows the Glacier Gorge Trail, one of the most scenic routes in Rocky Mountain National Park. The trail is beautiful from start to finish, passing waterfalls and subalpine forests before reaching the final scramble up to the lake. That last section involves a rock scramble that requires some hand-over-foot effort, but hikers consistently say the payoff is worth the work. The total round trip is roughly 9 miles with significant elevation gain, so come prepared with proper footwear and layers.

Seasonal conditions play a major role in planning your visit. Early-season hikers in June may encounter deep snowpack on the upper trail, with 3 to 4 feet of snow reported as late as mid-June in some years. Microspikes or traction devices are essential for navigating icy sections, and the scramble to the lake can be particularly slick when frozen. In winter, the lake itself freezes solid and truly looks like glass, but shoe traction is a must if you plan to walk across it. Summer months from July through September offer the most accessible conditions and the best chance at calm, reflective water.

Lake of Glass sits just a quarter mile below Sky Pond, and most hikers continue on to visit both. The panoramic views from Lake of Glass are extraordinary in their own right, with expansive vistas of surrounding peaks and alpine tundra. Many visitors find this spot so striking that it becomes the highlight of the trip, even with Sky Pond waiting ahead. Take time to rest here and absorb the scenery before pushing on.

Because this hike is within Rocky Mountain National Park, a valid park entrance pass or reservation is required during peak season. Start early to secure parking at the Glacier Gorge Trailhead, as lots fill quickly during summer months. There are no facilities at the lake, so carry plenty of water, food, and sun protection. Wind and cold temperatures are common at this elevation even in summer, so pack a windbreaker regardless of the forecast at the trailhead.
