Starting from the Hoh Rain Forest Visitor Center, the Hoh River Trail is a 17.5 mile trek through forests of Douglas Fir, Hemlocks and Big Leaf Maples with ever-present cougar, bobcat and elk. The first 11 miles of this rain forest hike are an easy, gradual ascent through lush rain forest. Sitka spruce, hemlock, red cedar, and bigleaf maple shelter a forest floor carpeted with an incredible array of plant life. The trail grows more difficult through a deep gorge past Elk Lake to Glacier Meadows. Plan to camp overnight if you hike to Glacier Meadows. A route to Mount Olympus begins beyond this point, a climb that should only be attempted by experienced mountaineers.
To reach the trailhead from Forks, head south on US101 for about 15 miles to the Upper Hoh Valley Road. Turn left heading east for about 16 miles to the end of the road. Use the parking lot at the visitor center for day hiking.
Overall, Hoh River Trail is the 2nd most popular hiking trail of all 56 hikes in Washington.
