Overview
Spanning over fifteen thousand expansive acres of open shortgrass prairie just a short drive from downtown Denver, the Rocky Mountain Arsenal National Wildlife Refuge is an incredible sanctuary for American wildlife. This unique property, formerly a historic military manufacturing site, has been beautifully restored into a thriving nature habitat where massive American bison, majestic deer, bald eagles, and playful prairie dogs roam completely free. Visitors can embark on a scenic eleven-mile self-guided auto tour, capturing incredible photographs of wild animals against the striking background of city skyscrapers.
Practical Info
Suggested Duration2-4 hours
Best TimeEarly mornings (6:00 AM to 8:00 AM) or dusk are the absolute best times to visit when bison, mule deer, prairie dogs, and raptors are most active. Autumn brings beautiful changing foliage and coincides with the wildlife's seasonal behaviors, making it perfect for photography.
Getting ThereLocated roughly 20 minutes northeast of downtown Denver. There is no direct public transit, making driving a necessity; take I-70 East to Quebec St and head north. Entry is free, and there is ample free parking at the visitor center and major trailheads.
Travel Tips
- While driving the 11-mile Wildlife Drive loop, it is strictly illegal to exit your vehicle, lean your body out of open windows, or drive off-road. Wild bison are unpredictable and aggressive; maintain a 25-yard car clearance. The entire loop is heavily patrolled at a strict 15 mph speed limit.
- As a sensitive federal refuge, operating or launching recreational drones anywhere on the property is illegal. Pets are completely prohibited inside the refuge bounds, even if confined within your personal vehicle (service animals excluded). Collecting shed antlers, bird feathers, or flora is a federal offense.
- Wildlife active hours peak at early dawn (6 AM–9 AM) and sunset (4 PM–6 PM); animals bed down out of sight during intense midday heat. Admission is free, but you must only park inside labeled asphalt lots at trailheads or the Visitor Center; pulling over on loop shoulders is illegal.
Reviews
Positive
- Completely free to enter! The wildlife drive loop is fantastic for spotting herds of bison up close.
- Besides bison, visitors frequently spot coyotes, deer, and raptors, making it a paradise for photographers.
- The modern visitor center features excellent interactive ecological exhibits, great for educating kids.

Heads up
- Animal sightings depend entirely on weather and timing; on unlucky days, you might drive the loop and see nothing.
- The self-drive route gets crowded on peak weekends, causing slow crawls and quite a bit of dust on dirt roads.
- Trails lack tree shade and get intensely hot in summer, requiring visitors to bring plenty of sun protection and water.
- As a former military/industrial site, some areas remain closed for ecological recovery, limiting exploration.
