Hanging Lake: Colorado’s Turquoise Lake in Glenwood Canyon

Hanging Lake is one of the most unusual sights in Glenwood Canyon, Colorado. The small lake is known for its clear turquoise water, pale mineral formations, and waterfalls that flow over moss-covered rocks. Set on a steep mountainside near Glenwood Springs, it looks quite different from an ordinary mountain lake.

Hanging Lake sits high above Glenwood Canyon in Colorado and is known for its clear water, mineral formations, and surrounding waterfalls.

The lake’s formation is linked to a geological fault and the gradual accumulation of travertine, a type of limestone deposited by mineral-rich water. Today, hikers and nature lovers visit Hanging Lake, but reaching it requires a steep uphill hike. Visitors must follow strict rules to protect its delicate formations and surrounding vegetation.

Where Is Hanging Lake?

Hanging Lake is located in Glenwood Canyon in western Colorado, United States, near the city of Glenwood Springs. The lake lies within the White River National Forest, along a dramatic section of canyon carved by the Colorado River. Although Interstate 70 passes through Glenwood Canyon, Hanging Lake is not a roadside viewpoint. Visitors must reach the designated trailhead and hike uphill to see the lake. Access is managed through a permit and timed-entry system to help protect the area from excessive visitor pressure. The lake is recognised as a National Natural Landmark for its distinctive geological features and sensitive natural environment.

How Was Hanging Lake Formed?

Hanging Lake sits in a rocky basin high above the floor of Glenwood Canyon. A geological fault helped create this unusual landscape by allowing part of the ground to drop. Water collected in the basin, and over thousands of years, mineral deposits helped shape the lake’s edges.

The Role of Travertine

Look closely at the edges of Hanging Lake, and you will notice pale rock formations around the water. These are associated with travertine, a type of limestone formed when mineral-rich water leaves behind calcium carbonate. As fresh water continues to flow over the rocks, new deposits can slowly build up. The formations take a long time to develop, so they need careful protection. Visitors are not allowed to enter the lake or walk over its delicate features. Staying on the designated paths helps preserve the area for future visitors.

Why Is the Water So Blue?

Hanging Lake is renowned for its striking blue-green colour. The clear water, the interaction of light with it, and the pale mineral deposits beneath and around the pool all contribute to its appearance. Water clarity and lighting can change how turquoise the lake looks from different viewpoints and at different times. The colour is one of the lake’s most recognisable features, but its delicate geological setting is equally important for understanding why the site is protected.

Bridal Veil Falls and Spouting Rock

Waterfalls are central to Hanging Lake’s appeal. Bridal Veil Falls feeds the lake, creating a continuous flow of water through the rocky basin. The sound of falling water, bright green vegetation, and pale travertine create the area's distinctive atmosphere. Another nearby feature is Spouting Rock, where water emerges directly from an opening in the rock face. This waterfall is located above Hanging Lake and offers a different view of the canyon’s water-shaped landscape. Together, the lake and waterfalls show how water continues to shape this unusual environment.

Hiking the Hanging Lake Trail

Reaching Hanging Lake involves a demanding uphill walk rather than a short stroll. The established trail is approximately 1.2 miles (1.9 kilometres) one way, with an elevation gain of about 1,200 feet (366 metres). Rocky steps, steep sections, and bridges over Deadhorse Creek make the route challenging for some visitors. Allow several hours for the round trip, including time to rest and appreciate the scenery. Wear sturdy footwear with excellent grip, carry enough drinking water, and dress for changing mountain conditions. The route can be slippery or icy in cold weather, and visitors should check current trail information before travelling. The effort pays off with views of the lake’s vivid water, mineral formations, and waterfalls framed by steep canyon walls. However, inexperienced hikers and anyone who struggles with steep climbs should not underestimate the trail’s difficulty.

Protecting Hanging Lake’s Fragile Environment

Hanging Lake’s beauty depends on a delicate balance of water, minerals, rocks, and plant life. Heavy visitor traffic can damage this environment, so access is regulated. Swimming, wading, and dipping body parts into the lake are prohibited. Visitors must not walk on the waterfalls or the fallen log in the water, and rubbish must be carried out. Pets are generally not allowed on the trail, except for qualifying service animals under the applicable rules. These restrictions may seem strict, but they help preserve the lake for future visitors. Staying on the trail and following posted instructions are essential parts of visiting this remarkable natural landmark.

Visiting Hanging Lake

A timed-entry permit is required to hike to Hanging Lake, and reservations should be arranged before travelling. As of October 2026, the official visitor information lists a permit fee of $12 per person, including parking. Fees, reservation availability, and access conditions can change, so check the official website before your visit. The trailhead is accessed from Interstate 70 at Exit 125 for eastbound traffic. Drivers travelling westbound should follow the official directions, as there is no westbound exit directly into the Hanging Lake rest area. Parking is restricted to permit holders, and oversized vehicles are not allowed. Restrooms are available at the trailhead, but there are no restrooms or drinking fountains along the trail or at the lake. Bring water and snacks, take your rubbish with you, and allow extra time for road conditions or weather delays.
