      About Us

      Rocky Mountain Arsenal National Wildlife Refuge was established in 2004, in part, to protect our national symbol, the bald eagle. The land has a unique story - it has survived the test of time and transitioned from farmland, to war-time manufacturing site, to wildlife sanctuary. It may be one of the finest conservation success stories and a place where wildlife thrives. 

      Tours

      One of the best ways to experience this 15,000 acre Refuge is by taking the 11-mile Wildlife Drive auto tour in your vehicle. Listen to the podcast, which corresponds with each mile marker along the way to discover more about the Refuge and its wildlife. The Wildlife Drive takes about 45 minutes to 1 hour to complete. 

      Know Before You Go:

      • The Wildlife Drive is open to motorized vehicles; speed limit is 30 mph.
      • Follow the directional symbols. Park vehicles only in designated areas on map.
      • Stay on paved roads and observe all posted signs such as "Stay in Vehicle" or "Area Closed".
      • Stay in your vehicle when the road becomes one way only.
      • Always stay at least 75 feet (23 meters) away from bison.
      • Be sure to view the Wildlife Drive and Trails Map for map and details.
