Boulder Lake — Olympic National Park

Boulder Lake sits deep in Olympic National Park's backcountry, accessible only by a demanding 7-mile hike that begins where the road to the original trailhead has closed. The first few miles follow relatively level terrain before reaching Olympic Hot Springs, where the route turns right and climbs steadily uphill for 3-4 miles to reach the lake. This remote location sees few overnight visitors according to available reports. Campers can set up along the lakeshore and take advantage of the lake for swimming after the long approach hike.
