Barr Lake State Park surrounds a reservoir of more than 1,950 acres with cottonwoods, marshes and aquatic plants. Its southern half is a wildlife refuge that shelters many birds and animals. Visitors can walk trails, watch birds from viewing points, fish, and visit the nature center. Boating is currently closed for the 2026 season because of low water levels, and a toxic algae alert advises avoiding contact with the water.
