Visting Parks with your Pets
In general, pets are permitted but must be restrained either on a leash not exceeding 6 feet in length, caged or crated at all times. Park Superintendents and Managers have the discretion to further restrict areas open to pets (i.e., trails, buildings, campgrounds may be off limits).

Some park webpages have lists of nearby kennels where you can leave your pet during your stay in the park. You can access information on the parks you plan to visit by going to the "Visit Your National Parks" website at http://www.nps.gov/parks.html. It is always best to check with the park(s) you are planning to visit for specific information and restrictions for pets.
