The reservoir southwest of town, between Timnath and Fort Collins, is a joint Fort Collins and Larimer County natural area of about 1,400 acres: rolling prairie, wetlands and a tree-lined reservoir that the National Audubon Society lists as an Important Bird Area, with wintering bald eagles, shorebirds and waterfowl, and coyotes, deer and prairie dogs. Three short trails from the Carpenter Road (Colorado 392) entrance: the quarter-mile paved Heron Loop with picnic shelters, the 0.4-mile Sandpiper Trail and the 0.76-mile Cattail Flats Trail to viewing blinds, with seasonal closures to protect eagle roosts. Hiking only: no dogs, bikes or horses. Dawn to dusk.
