The Long View Trail connects Fort Collins and Loveland along Shields Street and provides access to Colina Mariposa and Hazaleus natural areas (City of Fort Collins), Long View Farm Open Space (Larimer County) and Sunset Vista Natural Area (City of Loveland).
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 from the adjacent neighborhood and a section of the Long View Trail provides access to Colina Mariposa. Long View Trail connects Fort Collins and Loveland parallel to Shields Street.
