General Information

Rocky Flats National Wildlife Refuge

Lindsay Ranch

Established in 2007, Rocky Flats National Wildlife Refuge is managed by the U.S. Fish and Wildlife Service. The 5,237-acre Refuge has striking mountain vistas and rolling prairie grasslands, woodlands, and wetlands. It is home to 239 migratory and resident wildlife species, including prairie falcons, deer, elk, coyotes, songbirds, and the federally threatened Preble's meadow jumping mouse. A portion of the Refuge contains rare xeric tallgrass prairie, providing habitat for a variety of wildlife and serving as an important natural and conservation resource.

Refuge Opening Planned for Summer 2018

Proposed Trail System 3-18

We need to build visitor facilities such as a multi-use building, trails, parking areas, and signs before opening Rocky Flats National Wildlife Refuge to visitors. It is anticipated that construction of visitor facilities will begin this winter. Once the infrastructure is in place, Refuge staff hopes to open the Refuge to visitors in Summer 2018.
