Coot Lake

Coot Lake

About Coot Lake

Coot Lake is a scenic natural area with fishing, walking and jogging opportunities while experiencing nature. It is about 1.2 miles around the lake.

Nature Play Opportunities

Children have a wide variety of unique nature play opportunities at Coot Lake. A portion of Coot Lake is a wildlife reserve for wetland species, which provides ample opportunities for children to observe local species as well as to fish in other designated areas. The 1.2-mile trail around the lake has access to various short trails and the Boulder Reservoir and contains an art walk. The art walk displays prints of scenes and quotes from the lake that children may stop by and read during their walk around the lake. The art walk brings a new and creative perspective to the trail.
