Camping with pets near Mount Rainier National Park means hiding away from the world and enjoying peaceful seclusion in this beautiful corner of Washington state. The park contains an active volcano, the snow-capped Mount Rainier, which is the highest mountain in Washington. If you and your pet are looking for an activity-filled holiday, then you can hike to the top of it on the Wonderland Trail, or try the Sunrise Peak or Paradise Peak if you want to take it a bit easier. The landscape of meadows, forests, glaciers, and mountains is a treat for the senses. Your pet can run wild in over 90,000 acres of forestland, and return home to one of the great glamping rentals on offer that are very pet-friendly.
