Hoh Rain Forest

One of the largest temperate rain forests in the country — moss-draped maples and 300-foot Sitka spruce in a valley that catches twelve feet of rain a year. The Hall of Mosses and Spruce Nature Trail are short loops from the visitor center; the Hoh River Trail runs 17 miles back toward Mount Olympus and the Blue Glacier. It's a 90-minute drive in off US-101 on a dead-end road, so plan it as its own day.

Overview

Hoh Rain Forest — Olympic

One of the largest temperate rain forests in the country — moss-draped maples and 300-foot Sitka spruce in a valley that catches twelve feet of rain a year. The Hall of Mosses and Spruce Nature Trail are short loops from the visitor center; the Hoh River Trail runs 17 miles back toward Mount Olympus and the Blue Glacier. It's a 90-minute drive in off US-101 on a dead-end road, so plan it as its own day.

    Easy Loop Kid friendly

    A short, mostly flat loop through old-growth temperate rainforest in the Hoh Rain Forest, with moss-draped maples, towering Sitka spruce and Western hemlock, and nurse logs lined with young saplings. The Hoh Valley is one of the wettest places in the continental US, so expect damp, muddy footing and pack waterproof boots. The big logistical catch is access: in summer (June-September), limited parking can mean 1-2 hour waits at the Hoh entrance gate between 10am and 4pm, so arrive early. Dogs are not allowed.

    Hoh Rain Forest

    Short walk

    One of the largest temperate rain forests in the country, on the wet west side of the Olympics. The visitor center at the end of the 18-mile Hoh Road is the trailhead for the Hall of Mosses and Spruce Nature Trail — short loops under moss-draped maples and towering Sitka spruce and hemlock. This corner gets 12 to 14 feet of rain a year, so expect green, dripping, and quiet. The road and lot fill by midday in summer; arrive early.
