The Saltwater State Park will give you a sense of what Washington natural parks have to offer so it’s a great place to get started. It’s right within the city limits of Des Moines, on the town's south end. Expectedly, you will share the park with a good crowd when there's no cloud. Comb the sandy shore strewn with driftwood, take a dip in the shallows, or put on your fins for a dive to an artificial reef. Then put your camper rental in Des Moines to good use and see the snow-capped peaks, lush temperate forests, and rugged coastlines of the Olympic National Park. Encompassing an area close to a million acres, the park is home to several distinct ecosystems. Spy orange and purple starfish or the green-tentacled giant green anemone in the tide pools of Kalaloch's Beach 4 and Mora's Hole in the Wall during low tide. Give your legs a good workout in the park's extensive hiking trails passing through lowland forests, along beaches, or up mountain ridges. Or drive the scenic loop of the lush Quinault Valley in your Des Moines RV rental for a view of ice-carved peaks, shimmering lakes, and alpine meadows. For the keen climber, the alpine summits of the North Cascades National Park are hard to overlook. Close to 400 miles of trails crisscross the park's diverse and rugged terrain so you have no shortage of hiking options. Climb the glaciated slopes of the volcano Mt. Baker or take a quiet stroll along the river while looking out for migrating salmon, birds, and other wildlife. Glacial meltwater feeds the park's 600 lakes and 4,000 miles of rivers and streams so there are also plenty of opportunities to cast a line out for salmon or steelhead or navigate Class II rivers like the Queets and Hoh or Class V rivers like Quinault and Sol Duc.
