Trails in Washington
There are 4 National Park Service units that include territory in Washington. The directory below links to every park guide we maintain for the state. For multi-state parks, you'll see the same entry on each state's page — the trail catalog itself is identical.
Trip planning from Washington typically means balancing drive time against trail effort. A weekend out of state can be more efficient than a one-day push to a closer unit if it means daylight on the actual trail rather than behind the wheel. Use the per-park guides to compare difficulty and seasonality before locking in dates.
Mount Rainier National Park
Active glaciated stratovolcano towering 14,410 feet over old-growth forest, alpine meadows, and the highest density of glaciers in the lower 48.
North Cascades National Park
American Alps — over 300 glaciers, granite spires, and lush valleys in a rarely visited corner of Washington State.
Olympic National Park
Three distinct ecosystems in one park: glaciated peaks, temperate rainforests, and 73 miles of wild Pacific coast.
San Juan Island National Historical Park
Site of the bloodless 1859 "Pig War" boundary dispute between the U.S. and Britain in the San Juan Islands.
