Things to Do
Washington state parks offer an incredible diversity of outdoor recreation — from the rain-soaked old-growth forests of the Olympic Peninsula to the volcanic landscapes of the Cascades, the arid canyonlands of Eastern Washington, and the island-dotted waters of Puget Sound. Popular activities include hiking through moss-draped temperate rainforests, beachcombing on wild Pacific shores, kayaking through the San Juan Islands, camping beneath towering Douglas firs, fishing for salmon and steelhead in glacier-fed rivers, rock climbing basalt columns, mountain biking forested trails, and cross-country skiing in winter. Many parks also offer historical interpretation, including military forts, pioneer homesteads, and Native American cultural sites.
Best Time to Visit
Washington’s outdoor season varies dramatically by region. Western Washington (including the coast and Puget Sound parks) is driest and warmest from June through September — this is peak season. Spring and fall bring fewer crowds and mild temperatures but expect rain. Eastern Washington parks enjoy more sunshine year-round, with hot summers and cold, snowy winters. The San Juan Islands are best visited May through September for whale watching (orcas) and calm seas. Mountain parks in the Cascades open as snow melts, typically July through October. Winter transforms many parks into cross-country skiing and snowshoeing destinations. Always carry rain gear west of the Cascades, regardless of season.
Visitor Tips
Washington state parks require a Discover Pass ($45/year or $10/day) for vehicle access. Purchase one online through the Washington State Parks website before your visit — it covers all 100+ state parks. Camping reservations are made through the state parks reservation system up to 9 months in advance. Popular parks like Deception Pass and Cape Disappointment book months ahead for summer weekends. Many parks in the San Juans and islands are accessible only by ferry or boat — check Washington State Ferries schedules in advance. Cell service can be unreliable, especially on the coast and in mountain parks.

The park’s Columbia River reservoir provides fishing for walleye, smallmouth bass, and rainbow trout. White pelicans roost on sandbars. Bald eagles and osprey fish from heights.
