The park prohibits dogs (and other pets) on backcountry trails for several reasons:
• Dogs can carry disease into the park's wildlife populations.
• Dogs can chase and threaten wildlife.
• Dogs bark and disturb the quiet of the wilderness.
• Pets may become prey for larger predators such as mountain lions, coyotes and bears.
• Many people, especially children, are frightened by dogs, even small ones. Uncontrolled dogs can present a danger to other visitors.
Although not allowed on trails, pets are still permitted in Rocky Mountain National Park. According to the park website, pets:
"are allowed only in areas accessed by vehicles, including roadsides, parking areas, picnic areas and campgrounds. They must be kept on a leash no longer than six feet and attended at all times. Pet etiquette dictates always cleaning up after your pet and disposing of waste in trash receptacles."If you still wish to hike with your dog while visiting the Rocky Mountain National Park area, you do have a few options outside the park. There are several multi-use trails around the Town of Estes Park, as well as open space areas within the counties surrounding the park. Some of these include:

All trails in the Arapaho and Roosevelt National Forest, which surrounds Rocky Mountain National Park on all sides, are open to pets; however, some require pets to be leashed. You should always check first for information concerning a particular trail in the national forest. Hiking guides are available at ranger district offices. They describe the trails and identify special regulations, such as restrictions on dogs or horses, permit requirements, or other special trail regulations. You can also call:
