Where to Fish Glacier Lake


Glacier Lake is a relatively large (18.4 acres), remote glacial cirque lake located within designated Wilderness in the Rattlesnake Creek drainage near Missoula at ~ 6,980 ft elevation. In order to increase storage volume, the lake has been artificially impounded by a dam at the outlet. This structure elevates the normal surface water elevation, but may also contribute to greater annual water level fluctuations.

Size 18.4 acres
Elevation 6980.0 ft.
Directions Although this lake is geographically very close to the city of Missoula, access is difficult. There are several USFS routes from which to choose. Route distance and difficulty varies, but all require non-motorized travel. Common starting points are the trailheads at West Fork Gold Creek (Trail # 52), Ravine Creek in lower Grant Creek (Trail # 34), or in lower Rattlesnake Creek at the main Rattlesnake National Recreation Area trailhead (Gated Road #99). Please refer to USFS maps for specific travel routes and connecting trail numbers. Total travel distance from trailheads to lake ranges from 9-17 miles.
