Olympic National Park sprawls over 1,400 square miles (3,626 square kilometers) of green-soaked Washington wilderness. Hike through the UNESCO World Heritage Site's extensive network of hiking trails, backpack along the coastline, or kayak through its many rivers. Adrenaline junkies can head to the Olympic Mountains for mountaineering or venture out on a mountain biking excursion from nearby Port Angeles.
For a deeper understanding of the area, stroll through the park with a naturalist guide on a small-group Olympic National Park day tour from Seattle. Or leave long lines and traffic behind on an Olympic Mountains Seaplane Tour from Lake Washington, on which you can cruise over Mt. Olympus, Hurricane Ridge, the Hoh Rain Forest, and the Pacific Ocean.
