The lake sits atop a thin layer of travertine, a type of limestone deposited by mineral-rich spring water.
The turquoise color is produced by the reflection of light off dissolved calcium carbonate and the growth of cyanobacteria.
It is designated as a National Natural Landmark by the National Park Service.
The site was historically part of the White River National Forest but is now managed under strict conservation permits.
The trail leading to the lake gains approximately 1,200 feet in elevation over 1.2 miles.
Deadhorse Canyon, where the lake is situated, was carved by the Colorado River and ancient glacial activity.
Hanging Lake is a travertine geological formation suspended on the edge of a limestone cliff in Glenwood Canyon. The lake's distinct turquoise color is caused by carbonate minerals depositing on the lakebed. Water enters the basin via the Bridal Veil Falls, which spill over the limestone into the lake. The site is a National Natural Landmark recognized for its fragile ecosystem. Access is restricted to a permit-based system to manage environmental impact. The surrounding cliffs are composed of Mississippian-aged Leadville Limestone. Visitors reach the lake via a steep, rocky trail that ascends through Deadhorse Canyon. The area features a boardwalk to protect the lake's delicate travertine edges from foot traffic. Swimming, wading, and fishing are strictly prohibited to maintain water chemistry.
The designated wooden boardwalk viewing platform provides the optimal vantage point for the lake and the waterfalls.
A pre-purchased permit is mandatory for all hikers, as no on-site sales occur.
Bring more water than you think you need, as the incline is steep and the climate is arid.
Wear footwear with significant tread and ankle support to navigate the final rocky, slippery scramble.
Do not attempt the hike without a confirmed, printed, or digital permit; arriving without one will result in being denied access.
Permits are required year-round; the trail may close temporarily during winter due to ice, avalanche risk, or heavy trail damage.
No swimming or touching the water; stay strictly on the marked trail and boardwalk to protect the fragile travertine floor.
