Size: 45-acre park

Coot Lake is Boulder's quiet lake option. While Boulder Reservoir draws crowds for swimming and water sports, Coot Lake offers solitude. The 1.2-mile trail circling the lake is flat, easy, and rarely crowded. Excellent spot for morning walks, evening fishing, or birding any time.
Activities
Fishing
Stocked with trout, bass, and bluegill. Colorado fishing license required. Fish from shore—no boats allowed. Early morning and evening produce the best catches. The lake is shallow, so fish congregate near the deeper sections on the east side.
Birdwatching
Named for the American coots that live here year-round. Also home to herons, egrets, cormorants, and various ducks. The cattail marshes along the edges provide habitat for red-winged blackbirds. Bring binoculars—the birdlife is surprisingly diverse for such a small lake.
Walking & Running
The 1.2-mile loop trail is flat, gravel-surfaced, and dog-friendly (leashed). Connects to the trail system that runs to Boulder Reservoir. Popular with dog walkers and joggers who want a peaceful route away from Boulder Creek Path crowds.
