The Rawah Lakes Trail in Roosevelt National Forest penetrates the Rawah Wilderness in the mountains northwest of Fort Collins, Colorado, reaching a chain of alpine lakes set in broad subalpine meadows at over 11,000 feet. This is one of the finest alpine lake destinations in northern Colorado, offering genuine wilderness character and wildflower-rich terrain that peaks in late July.
The Rawah Wilderness is less visited than many Colorado wilderness areas, which shows in the solitude available even on summer weekends. The 2,000-foot climb is earned but the payoff at the lakes is substantial.
The Route
From the Glendevey-area trailhead, the trail follows the West Branch of the Laramie River upstream through forest before climbing into the open subalpine zone. The transition from forest to meadow at around 10,500 feet is abrupt and dramatic: the views open across wide alpine terrain with the lakes glinting ahead.
The first lake is reached at approximately 3.5 miles, with additional lakes accessible by continuing on the main trail or via short side paths. The meadows surrounding the lakes are the wildflower highlight, with peak bloom in late July.
What to Expect
The high elevation means altitude adjustment matters. Hikers coming from lower elevations benefit from spending at least one night in the area before attempting this trail. Physical symptoms of altitude such as headache and shortness of breath are common and should be monitored.
Afternoon thunderstorms are a reliable feature from July through August in the Rawah. The open meadow and lake terrain provides no shelter from lightning; start early and plan to be descending by early afternoon.
Nearby
Fort Collins, Colorado, is about 70 miles southeast via CO-14 and US-287, and serves as the gateway city for the Roosevelt National Forest's northern section. The town of Glendevey is a small community near the trailhead with minimal services. CO-14 through Poudre Canyon is one of Colorado's most scenic mountain drives.
Leave No Trace
This trail receives enough use that following Leave No Trace principles is important for preserving the experience for future visitors. Stay on the marked trail to prevent erosion. Pack out all waste. Avoid camping within 200 feet of water sources or the trail. Use existing fire rings only where campfires are permitted, and check current fire restrictions at checking conditions before you go before any visit. The trail and surrounding terrain remain in good condition because previous visitors have respected these norms.
