Hiking in Washington covers a remarkable range of terrain inside the Pacific Northwest temperate rainforest and Cascade volcanic belt, from low-elevation walking paths to long backcountry routes deep in protected wilderness. Trail Compass currently lists 4 parks and 35 trails for Washington, accounting for roughly 248 mapped trail miles in total.
By difficulty rating, the Washington catalog breaks down to about 13 easy, 16 moderate, 5 hard, and 1 expert hikes. State parks, national forests, recreation areas, and a handful of NPS units all sit inside this index. Each parcel has its own permit rules, parking situation, and seasonal access — confirm current details with the managing agency before your visit, especially during winter or in fire-affected regions.
Best season to hike across most of Washington runs mid-July through early October for high country; lower forest trails are hikeable nearly year-round in mild rain gear. Outside that window, expect more variable conditions, possible road closures at higher elevations, and a much shorter daylight window for long routes.
Wildlife you can expect across Washington trails includes Roosevelt elk, black-tailed deer, Steller's jays, pileated woodpeckers, and salmon spawning in the autumn streams. Most hikers go years without an aggressive encounter, but every season produces a few — store food correctly, give predators wide berth, and never approach a young animal even when no parent is in sight.
If you are new to Washington, start with shorter, well-signed routes near major visitor centers. They give you a feel for the local terrain, weather patterns, and trail surface before you commit to a longer outing. Carry water, sun protection, and an offline map; cell service in Washington backcountry is intermittent at best.
