Green Lake is a small but visually striking alpine lake in Clear Creek County, nestled in the mountains west of Georgetown along the corridor between the Front Range and the Continental Divide. With a perfect 5.0 rating from visitors and a reputation as a place people describe simply as special, this lake punches well above its size when it comes to scenery and atmosphere.
The lake sits at approximately 10,400 feet in a glacially carved basin surrounded by steep forested slopes and exposed rock faces. The water takes on a distinctive green hue that gives the lake its name, a result of glacial flour and mineral deposits in the surrounding geology. On clear days, the reflection of the surrounding peaks on the calm surface creates the kind of postcard-quality scene that draws photographers from across the state.
Access to Green Lake involves a moderate hike through mixed conifer forest and subalpine meadows. The trail gains steady elevation without extreme steepness, making it manageable for hikers with a reasonable fitness level. The surrounding forest provides shade on hot summer days, and the final approach to the lake opens into a scenic basin where you can spread out along the shoreline for lunch or simply sit and take in the mountain views.
Green Lake attracts visitors who value peace and natural beauty over developed amenities. There are no restrooms, picnic tables, or other facilities at the lake, and that is part of what makes it feel special. The lack of heavy infrastructure keeps the area quiet and the visitor count low. Reviewers writing in multiple languages all share the same sentiment: the lake and its mountain setting are beautiful, and the experience of being there is worth the effort to reach it.
The lake is best visited from late June through early October, with July and August offering the most reliable weather and trail conditions. Wildflowers dot the meadows along the approach during midsummer. Fall brings patches of golden aspen at lower elevations and a crisp alpine atmosphere that makes hiking comfortable. Winter access is possible on snowshoes, though the trail is not maintained and route-finding skills are necessary. Georgetown, just a short drive east on Interstate 70, provides gas, food, and lodging for those planning a day trip or weekend visit to the area.
