Irene Lake

Lake Irene is a small, stunning alpine lake perched along Trail Ridge Road in Rocky Mountain National Park, Larimer County. Sitting at approximately 10,700 feet, this gem of a lake offers one of the easiest alpine lake experiences in all of Colorado. A short, well-maintained trail leads directly from the parking area to the lakeshore, making it accessible to visitors of nearly all fitness levels. The lake earns a near-perfect 4.9 rating from visitors who are drawn to its mirror-like reflections and serene mountain atmosphere.

The trail to Lake Irene is brief, flat, and winds through a mature subalpine forest of Engelmann spruce and subalpine fir. The entire walk takes roughly 10 to 15 minutes, and the payoff is immediate: a glassy alpine lake reflecting the surrounding conifers with postcard precision. On calm mornings, the water surface becomes a near-perfect mirror, making this one of the most photographed small lakes in Rocky Mountain National Park. The short distance and gentle grade make Lake Irene a favorite stop for families, older visitors, and anyone looking for alpine beauty without a strenuous hike.

Wildlife is a significant draw at Lake Irene. Visitors frequently encounter large elk herds grazing in meadows near the trailhead, particularly during early morning and evening hours. The surrounding forest supports a range of bird species, and the quiet setting rewards patient observers. Picnic benches and tables near the parking area provide a comfortable spot for a quick meal with a mountain backdrop before or after the walk.

Lake Irene is accessible only when Trail Ridge Road is open, typically from late May through mid-October depending on snowfall. The parking area is small, accommodating roughly a dozen vehicles, so arriving early is essential during peak summer months. Vault toilets are available adjacent to the parking lot. Snow can linger around the lake into June, adding a wintry element to early-season visits.

As a stop along Trail Ridge Road, Lake Irene pairs well with other Continental Divide attractions including the nearby continental divide marker and Poudre Lake. The lake sits near the headwaters of the Colorado River drainage, adding geographic significance to its natural beauty. For visitors touring Rocky Mountain National Park, Lake Irene delivers an outsized reward for minimal effort and stands as one of the most accessible alpine lake experiences in Colorado.
