Natural Area: Bike, Birding, Hike, Picnic, Walk
A unique feature of Colina Mariposa Natural Area is the high butterfly diversity on the eastern ridge, which led to the site name, Colina Mariposa – Spanish for “butterfly hill.” Bald eagles, turkey vultures, northern harriers, red-tailed hawks, and ferruginous hawks also use the habitat here. Approximately 1 mile of soft surface trail is accessible only from the adjacent neighborhood. In the future, the Fort Collins/Loveland bike trail is planned to traverse Colina Mariposa parallel to Shields Street.
