Dogs and Horses on County Open Space

Hiking with your dog or riding horseback on open space trails is a great opportunity for both you and your dog or horse to enjoy nature close to home. Dogs, horses, and other pets are allowed on most Boulder County's open space trails with some exceptions, noted below.

Follow all open space rules and regulations by reading the kiosk at the trailhead.

Dogs

Finding a Balance:
Resource Protection and Public Enjoyment

Boulder County parks and Open Space trails offer great opportunities for dogs and their owners to enjoy leashed adventures together. In fact, over one-hundred-thousand dogs explore these trails every year. County parks are also home to wildlife like mountain lions, black bears, mule deer, songbirds and raptors.

Dogs are allowed on all county open space trails, except those at Caribou Ranch, Hall Ranch, Heil Valley Ranch and Dodd Lake, which are considered prime wildlife habitat areas. See map below for properties and a list of off-leash exceptions.

Boulder County Parks and Open Space is charged with providing recreation for the public, and also protecting wildlife and their habitat. The cumulative impact of so many dogs can have a tremendous effect on local wildlife. One of the ways we protect wildlife is by requiring all dogs to be on a leash and under control at all times.

Some benefits of having your dog on a leash include:

  • Knowing your dog is safe from hazards like rattlesnakes, lions and cacti

  • Knowing your impact on native wildlife habitat is minimized

  • Having friendly interactions with other park visitors

  • Improving your chances of seeing wildlife

  • Avoiding an expensive ticket

Enjoy the benefits of keeping your dog on a leash in Boulder County Parks and Open Space. Happy trails!

Off-Leash Dog Areas for County Open Space

Reynolds Ranch open space is one exception to the leash rule and currently allows dogs off-leash. Also, the west lake at Twin Lakes is a dog off-leash area. Please note that as of April 14, 2007, the east lake will be leash-required and will be enforced.

Remember, without a leash, even friendly dogs can be a menace to wildlife and other users, especially children. Using a leash can also help reduce the risk of serious injury to your dog.

Any owner/guardian accompanying a dog in an off-leash area must have the ability to restrain his or her dog when requested by POS staff. No dogs are allowed to harass users or engage in threatening behavior which creates a nuisance for any user, domestic animal, or livestock.

Please remember to pick up, carry out and properly dispose of all dog excrement.

Horses

Equestrian on Nighthawk Trail at Hall Ranch.Horses and pack animals are allowed on all open space trails except on the Lichen Trail at Heil Valley Ranch and in incorporated areas within Lafayette and Louisville.

Horses are prohibited on Coal Creek/Rock Creek trails within incorporated areas. Trails outside the incorporated areas, including Coalton Trail, Mayhoffer/Singletree, the new spur on Imel and all trails on Rock Creek Farm do allow horses.

Equestrians should also be aware that the Walker Ranch Loop Trail includes a 500-foot cliff-like section of stone steps that is not recommended for horses.

Equestrians are encouraged to stay on designated trails. Again, because of the large number of hikers, bikers, equestrians and dogs on open space trails, horses must be under the physical control of a person at all times. The following guidelines will help make your ride more pleasant.

  • Check out the open space trails first before saddling up.
  • Make sure the horse is shoed, many trails are rocky.
  • Even though other users are expected to yield to equestrians, assume that they are not aware of trail etiquette.
  • Treat other visitors with courtesy and respect.
  • Make others aware of your intention to pass by calling out "passing", then pass with care.
  • Trailer parking is limited and in high demand, please refrain from parking your trailer in spaces not designated as trailer parking.
  • Avoid using the trails when they are muddy. If you encounter a muddy section on the trail, ride through it not around it.
  • Please use weed-free hay when feeding horses at open space trailheads. The spread of aggressive, non-native plants is a large problem in Colorado. Once these aggressive weeds become established, they are difficult, if not impossible, to eradicate.
