Frequently Asked Questions

The Colorado Front Range National Wildlife Refuge Complex (Rocky Mountain Arsenal National Wildlife Refuge [RMA], Two Ponds National Wildlife Refuge [TP], and Rocky Flats National Wildlife Refuge [RF]) is administered under the U.S. Fish & Wildlife Service (Service) by the National Wildlife Refuge System. Recreational opportunities at the Refuges are limited to wildlife dependent recreational opportunities that are compatible with the primary goal of promoting and ensuring wildlife, habitat, and ecological conservation and rehabilitation. Rules and regulations, which prohibits certain activities on refuge lands, have been created for the protection of wildlife, habitat, and visitor safety.


Q. Can I bring my dog (pet) to the Refuge / walk my dog on the trails?

A. Dogs (pets) are not allowed on all three Colorado Front Range National Wildlife Refuges (RMA, TP, & RF). Bringing your dog to a national wildlife refuge can be very disruptive to wildlife and some visitors.

Many wildlife species perceive dogs (pets) as a predator and in some instances as prey to larger predatory species. Dogs (pets) can chase wildlife or be a visual threat to wildlife and birds, causing wildlife and birds to flee nesting, burrowing, feeding, and resting sites. The lingering scent of the dog (pet) can signal the presence of a predator, long after the dog (pet) is gone. The disturbance of wildlife burns much needed energy that animals need to survive and raise their young.

Dogs (pets) can carry disease into the refuge’s wildlife populations. Dogs could unknowingly carry canine distemper, which can be detrimental to the health of our endangered black-footed ferrets and other small mammals. Dogs bark and disturb the quiet of the refuge. Unfamiliar sights, sounds, and smells can disturb even the calmest, friendliest, and best-trained dog, causing them to behave unpredictably or bark excessively.

Dogs and other pets brought to the refuge for a drive on the auto tour route must remain inside the vehicle while on the Refuge and should not be allowed to disturb or harass wildlife.

Note: Service animals are allowed, but must be on leash control at all times. The definition of a service animal is any animal that is individually trained to do work or perform tasks for the benefit of an individual with a disability. The crime deterrence effects of an animal’s presence and the provision of emotional support, well-being, comfort, or companionship do not constitute work or tasks for the purposes of this definition.

Emotional support, therapy, or comfort animals do not qualify or meet the definition of a service animal under the Americans with Disabilities Act (ADA). For more information on service animals please refer to the Department of Justice Civil Rights Division’s “Frequently Asked Questions about Service Animals and the ADA” pdf file

Q. Since I cannot hike / walk with my dog (pet) pet on the Refuge, Where can I walk my dog (pet)?

A. As an alternative, visitors can walk dogs on leash along the perimeter trail, located just outside the Rocky Mountain Arsenal NWR’s boundary. The trailhead and parking are located just before the Refuge entrance on Gateway Rd. It’s a great way to see Refuge wildlife, without impacting you, your dog, or the wildlife.

Q. Can I fly my drone / Unmanned Aircraft Systems (UAS) at the Refuge?

A. The use of drones / UAS are not allowed on all three Colorado Front Range National Wildlife Refuges (RMA, TP, & RF). Drones / UAS are prohibited from launching, landing or being operated from Refuge lands. Drones can be perceived as an aerial predator to wildlife and birds, causing wildlife and birds to flee nesting, burrowing, feeding, and resting sites. The disturbance of wildlife burns much needed energy that animals need to survive and raise their young. Some drones may produce excessive noise disturbing the wildlife and the quite of the refuges.

In addition to drone flight not aligning with the National Wildlife Refuge System’s primary focus on wildlife dependent recreational opportunities, the Rocky Mountain Arsenal NWR is under Class “B” Airspace administrated by the Federal Aviation Administration (FAA) due to it’s close proximity to Denver International Airport, which restricts the flight of aircraft (quadcopter, model planes, drones, UAS, etc.) from surface level to 12,000’ MSL.

Q. Can I ride my bicycle on Refuge roads and/or trails?

A. Bicycling is not allowed on roads or trails at two of the three Colorado Front Range National Wildlife Refuges (RMA & TP). Bicycling is permitted on designated trails at Rocky Flats NWR (RF). Although bicycling may be seen as a way to view wildlife, many songbirds, nesting birds, mammals, and wildlife with young view the fast motion of bicycling as a potential predator. Fleeing from a predator burns much needed energy that animals need to survive and raise their young. Additionally, Refuge roads were not designed for both cars and bicycles.

Bicycles are allowed from the RMA main entrance to the RMA Visitor Center. Bike racks are located just a few steps away from the Visitor Center building entrance and hiking trails start on the east side of the Visitor Center.

Q. Since I cannot ride my bicycle on the refuge (roads and trails) at RMA and TP, where can I ride my bicycle?

A. Bicycling is permitted on designated trails at Rocky Flats NWR (RF). As an alternative, bicycles are allowed on the perimeter trail (gravel trail), located just outside the Rocky Mountain Arsenal NWR’s boundary. The trailhead and parking are located just before the Refuge entrance on Gateway Rd. Other multi-user trails and parks around the refuges can be found at the following:

Q. Can I run / jog at the Refuge?

A. Running / jogging is not allowed on roads or trails at the Rocky Mountain Arsenal NWR. Running / jogging is permitted on designated trails at Two Ponds (TP) and Rocky Flats NWR (RF). Although running/jogging may be seen as a way to view wildlife, many songbirds, nesting birds, mammals, and wildlife with young view the fast motion of running/jogging as a potential fast moving predator. Fleeing from a predator burns much needed energy that animals need to survive and raise their young.

Q. Since I cannot run / jog on the refuge (roads and trails), where can I run / jog?

A. Running / jogging is permitted on designated trails at Rocky Flats NWR (RF). As an alternative, jogging and running are allowed on the perimeter trail (gravel trail), located just outside the Refuge’s boundary.
