      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. 


      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 and is free.
