Olympic National Park is Washington at its wildest and wettest: glacier-cut mountains, moss-draped rainforest, cold Pacific beaches, and deep blue lakes packed into one peninsula. Few American national parks change character so quickly. In a single long day you can stand in alpine wind at Hurricane Ridge, walk under giant maples in the Hoh Rain Forest, and finish beside sea stacks at Rialto Beach.
The park is not arranged around one central road. Instead, roads poke in from the edge toward different ecosystems, which means planning matters. Port Angeles is the most practical northern base for Hurricane Ridge, Lake Crescent, and the Elwha; Forks works for the Hoh and the beaches; Lake Quinault sits near the green, rain-soaked southwest.
Do not rush it. The distances are longer than they look, and the best parts of Olympic reward slow walking: the Hall of Mosses, the driftwood beaches, the view across Lake Crescent, the climb toward Mount Olympus if you have the skill and time. Summer brings the easiest access, but mist and rain are part of the park's personality, not a flaw in the experience.
