One of the most beautiful and remote campgrounds in the ONP, Hoh Rain Forest is accessed only by driving to the far western park perimeter on Hwy 101, then back east 18 miles (29km) into the heart of the rainforest. This road hugs the Hoh River all the way to its end at the Hoh Rain Forest Visitor Center and the campgrounds.
During peak season, many campers failing to find a landing point along the northern peninsula or Lake Crescent will end up here later in the day. Despite its remoteness, the rain forest brings many tourists and this campground can easily fill up for the weekend by Friday afternoon. Beyond campers, the area is also frequented by backpackers looking to enter the ONP Interior via the Hoh River Trail, which links up with other trails in the northern ONP and eventually leads to Mt Olympus.
The Hall of Mosses is considered a gem of the peninsula, and the rainforest abounds with massive old trees including some of the largest known of the common local species, such as Douglas Fir and Western Hemlock. True to its name, the Hoh Rain Forest is one of the wettest regions in Washington, receiving a yearly average of 140in (3.5m) of precipitation.
