Three distinct ecosystems within one park: rainforest, coast, alpine.
Washington camping covers three NPS units (Olympic, Mt. Rainier, North Cascades), the densest temperate rainforest in the lower 48 (Hoh, Quinault), and the Puget Sound island archipelago. Late snow on Cascade passes, coastal tides, and wilderness permit lotteries shape every trip.
