Pets are welcome at Crater Lake National Park, but only in certain areas. Pets on leash are allowed on paved roads and in parking lots, and up to 50 feet away from paved areas. One great place to walk your dog is along the 1/4-mile paved promenade at Rim Village, where you (and your dog) can get fine views of the lake. You can also walk your dog through the campground at Mazama Village.
