There are two excellent loop hikes winding through primeval forest with huge trees, dripping moss and the plants, ferns and lichen creating a mosaic of green. First, the iconic Hall of Mosses trail is .8 of a mile through the old growth temperate rain forest. The Spruce Nature Trail is 1.2 miles and gives you views of not only the rain forest but the Hoh River as well. There is also a short accessible paved loop of .1 miles that makes the rain forest accessible for everyone to explore. For those seeking a longer rain forest experience, the Hoh River trail goes up the valley 18 miles to the base of Mount Olympus. Day hike out and back as far as you like, or take a multi-day backpacking adventure.
