Things to Do

Washington state parks offer incredible diversity — from rain-soaked old-growth forests and volcanic Cascade landscapes to arid eastern Washington canyonlands and island-dotted Puget Sound waters. Popular activities include hiking through temperate rainforests draped in moss, beachcombing on wild Pacific shores, kayaking the San Juan Islands and Puget Sound, camping beneath towering Douglas firs and Western red cedars, fishing for salmon and steelhead in legendary rivers, and cross-country skiing in the Cascade mountain parks during winter.

Best Time to Visit

Western Washington parks are driest and most pleasant from June through September, when the typical overcast clears and reveals stunning scenery. Eastern Washington enjoys more sunshine year-round but can be extremely hot in summer. The San Juan Islands parks are best May through September for whale watching and kayaking. Mountain parks open as snow melts, typically July through October for higher elevations. Always carry rain gear when visiting parks west of the Cascades, as weather can shift rapidly.

Visitor Tips

A Discover Pass ($30/year or $10/day) is required for vehicle access to all state parks and recreation lands. Popular parks like Deception Pass — Washington’s most visited state park — book campsite reservations months ahead during summer. Many island parks (like Lime Kiln and Spencer Spit) are accessible only by Washington State Ferries — check ferry schedules in advance and expect long wait times during peak summer weekends. Some remote parks offer primitive camping only.
