A complete guide to camping in Washington

Washington State camping divides along the Cascade Range. The western side faces the Pacific, with Olympic National Park's rainforest, the San Juan Islands, and Puget Sound providing coastal and temperate forest camping in one of the wettest climates in the lower 48. The eastern side drops into dry shrub-steppe and irrigated farmland, a different world from the green west.
The Olympic Peninsula and North Cascades draw the most dedicated camping traffic. Port Angeles, Forks, and the Hoh Rainforest corridor see heavy summer use. East of the mountains, the Methow Valley and Leavenworth offer pine-forest camping with more predictable sunshine. Mount Rainier sits between the two zones, visible from campgrounds on all sides. Rockport, Naches, and Cle Elum serve as access points to the Cascade backcountry. The state park system maintains campgrounds on ocean beaches, mountain lakes, and river corridors throughout both halves of the state.

Coastal · Port Angeles, Forks, Sequim, Hoodsport
Temperate rainforest, rugged Pacific coastline, and alpine peaks all within Olympic National Park. The Hoh Rainforest receives 140 inches of rain annually. Coastal campgrounds at Kalaloch and Mora sit behind drift-log beaches. Port Angeles and Forks serve as supply towns. Summer is the only dry window. Elwha RV Park and Campground and Crescent Beach RV Park near Port Angeles serve the northern park access, while Quileute Riverview RV Park in Forks covers the western rainforest side.
Mountain · Rockport, Marblemount, Winthrop, Stehekin
Remote alpine terrain with glaciated peaks and old-growth forest. North Cascades National Park and the surrounding national forest offer both developed campgrounds and backcountry sites. Rockport and Stehekin (accessible only by boat or foot) anchor the access points. Heavy snowpack limits the season to June through October. Glacier Peak Resort and RV Park in Rockport and Colonial Creek South Campground provide developed options along the Highway 20 corridor.
Mountain · Naches, Packwood, Ashford, Enumclaw
The state's iconic volcano with campgrounds at multiple elevations. Cougar Rock and Ohanapecosh are the primary developed options. Sunrise sits highest at 6,400 feet. Naches and Packwood provide private campground alternatives outside the park boundary. Elk Ridge Campground and Squaw Rock RV Resort near Naches serve the east-side access, while Packwood RV Park covers the southern Ohanapecosh entrance.
Coastal · Orcas Island, San Juan Island, Anacortes, Whidbey Island
Island camping accessible by ferry. Moran State Park on Orcas Island is the most sought-after destination. Lopez and San Juan Islands have smaller campgrounds. Deception Pass State Park on the mainland side draws heavy day-use and overnight traffic. Mild maritime climate year-round. Quarry Pond Campground at Deception Pass State Park near Oak Harbor provides the most accessible island-area camping on the mainland side.
Plains · Leavenworth, Cle Elum, Winthrop, Ellensburg
Dry pine forest and open steppe east of the Cascades. The Methow Valley near Winthrop and Leavenworth's Bavarian-themed town attract summer visitors seeking sun. The Columbia Plateau stretches south toward the Tri-Cities. Summer temperatures reach the 90s. Less rainfall means more predictable camping weather. Icicle River RV Park in Leavenworth and Whispering Pines RV Park in Cle Elum anchor the eastern Cascade foothills camping corridor.

Three ecosystems in one park: temperate rainforest, alpine wilderness, and 73 miles of wild Pacific coastline on Washington's Olympic Peninsula.

July and August are the driest months statewide and the only reliable window for mountain camping. June can still be wet on the west side. September extends good conditions most years. Coastal camping is possible year-round but expect rain from October through May.
The Hoh Rainforest receives 140 inches of rain annually, most of it between October and May. Summer (July and August) is remarkably dry by comparison. Coastal campgrounds at Kalaloch and Rialto Beach get less rain than the interior valleys but more wind.
Popular state parks book out months ahead for summer weekends. Deception Pass, Moran, and Cape Disappointment are the hardest to get. Reservations open nine months in advance. Walk-up sites exist but are limited at popular locations.
National forests throughout the Cascades permit dispersed camping. The Okanogan-Wenatchee, Mount Baker-Snoqualmie, and Gifford Pinchot national forests have extensive options. No permits required for most dispersed camping. Check fire restriction status before building campfires.
A $30 annual vehicle pass (or $10 day pass) required for parking at Washington State Parks and DNR recreation lands. It does not cover national park or national forest fees. Purchase online or at the park entrance. One pass covers two vehicles registered to the same household.
