Dogs are welcome in parts of Olympic National Park. Leashed dogs are allowed on Peabody Creek Trail, Rialto Beach parking lot to Ellen Creek, the beaches between Hoh and Quinault Reservations, Madison Falls Trail, Spruce Railroad Trail, and July Creek Loop Trail. They are also welcome in campgrounds and picnic areas, as well as paved or dirt roads. Pets are not allowed on all other trails, in public buildings, on interpretive walks or in the wilderness. Dog owners are responsible for cleaning up after their pets and making sure they don't dig, roll on the plants or harass the wildlife.
Be sure to check out Olympic National Park's official website for information on admission, and to find out how Fido can become a Bark Ranger and earn a Bark Ranger Badge!
