The Hoh Rain Forest, in Olympic National Park, is a rare temperate rainforest where giant trees draped in moss create a primeval landscape. One of the wettest places in the contiguous US, its lush canopy of Sitka spruce and bigleaf maple shelters a vibrant understory of ferns and lichens. A UNESCO World Heritage site, it offers year-round discovery along gentle trails, with the Hoh River providing habitat for Roosevelt elk. Its quiet, green ambiance invites contemplation of an ancient, living world.
Best season — July through September offer the driest conditions, though the forest is lush year-round.

The Hoh Rain Forest is a rare temperate rainforest within Olympic National Park, recognized as a UNESCO World Heritage Site. It’s significant for its abundance of life sustained by high annual rainfall and old-growth trees draped in mosses and ferns. This unique ecosystem provides habitat for Roosevelt elk and invites quiet observation of an ancient landscape.
RV travelers explore the Hoh Rain Forest via accessible trails like the Hall of Mosses Trail and the longer Hoh River Trail, both offering views of towering conifers and bigleaf maples. The soft, moist atmosphere is a defining characteristic, allowing visitors to experience a cathedral-like grove filled with vibrant understory plants.
July through September generally provide drier conditions for visiting the rainforest, though its lush beauty persists throughout the year. Seasonal variations impact rainfall amounts and wildlife activity; current conditions should be checked before arrival. The forest remains accessible regardless of time of year, offering unique experiences in all seasons.
Consider establishing a basecamp outside the immediate area to facilitate exploration of the Hoh Rain Forest. From there, plan day trips into this remarkable ecosystem, allowing ample time for walking trails and observing wildlife. This approach provides both access to the forest's tranquility and convenient RV amenities.
