Olympic National Park: Hoh River Trail to Blue Glacier - Backpacker

Olympic National Park: Hoh River Trail to Blue Glacier

Hike through temperate rain forest alongside the Hoh River to the tip of the Blue Glacier--the largest glacier in Olympic National Park--and 7,980-foot Mt. Olympus towering above the ice.

Climb to the base of Mt. Olympus on a 33.2-miler that dead-ends at the toe of 2.6-mile-long Blue Glacier, the largest sheet of ice in Olympic National Park. Meander east on the Hoh River Trail through a primeval forest of gargantuan red cedars, Sitka spruce, and big-leaf maples. Set up basecamp at mile 9.9 in Lewis Meadow (campfires allowed), or choose a more solitary site along the countless gravel bars that flank the trail. The next morning, tackle the remaining 6.7-mile climb (and 3,700 feet of elevation gain) that leads right to the edge of the 900-foot-thick glacier on Olympus’s north face.
