The West Coast’s rain forests are at their best once the rain returns, and the California one drops its permit in October

Most people chase sunshine on the West Coast, but the best forest walks happen when it’s damp. Rain is exactly what built the moss-draped, fern-wrapped places on this list, and October is when the weather finally starts matching the scenery.

Three states, three temperate rain forests, and none of them takes more than an hour on foot. Which one fits your trip?

Washington: the Hoh, where the rain is the main event

The Hoh Rain Forest in Olympic National Park gets about 140 inches of precipitation a year, which is the whole reason hundreds of mosses and ferns carpet the floor beneath the trees. Two short loops start near the visitor center: the Hall of Mosses is 0.8 miles, and the Spruce Nature Trail is 1.2 miles along Taft Creek and the Hoh River.

Pick the Hall of Mosses first. The maples there are draped in club moss so thick it looks like the trees are wearing coats, and the whole loop is easy enough for a rainy-day shoe.

One planning note: the visitor center is generally open Friday through Sunday in fall, so a weekend trip gets you the full setup. Our longer breakdown of the Hoh’s trails covers the river hikes past the loops.

Oregon: Cape Perpetua, rain forest with a coastline attached

Oregon’s version sits on the central coast at Cape Perpetua, inside the Siuslaw National Forest. The Giant Spruce Trail is a 2-mile there-and-back from the visitor center, mostly easy, following Cape Creek up a narrow valley through old-growth coastal forest.

The payoff is a Sitka spruce around 500 years old and over 185 feet tall, with a trunk more than 40 feet around. The 1962 Columbus Day storm took the top 35 feet off it, and it still looks enormous.

Here’s the bonus: the same cape holds one of the coast’s best storm-season stops. Pair the forest with Thor’s Well and you get two very different kinds of wet in one afternoon.

California: Fern Canyon, the one you wade through

Fern Canyon in Prairie Creek Redwoods State Park is my pick if you only get one. A creek runs right through the bottom of a narrow gorge, and the walls are stacked floor to ceiling in ferns, so expect to splash through the water instead of staying dry. The loop is about a mile.

Here’s the October news. The reservation system for the Gold Bluffs Beach day-use area, which includes the Fern Canyon trailhead, is a summer thing, and by October it’s off, so you can show up without planning weeks ahead. Day-use fees can be covered by an America the Beautiful Pass or a California State Parks pass. Our guide to Fern Canyon has the details, including the longer free route from the Prairie Creek visitor center.

How to string them together

Doing all three means a long drive down the coast, but each stop needs less than an hour on foot. Start at the Hoh, roll south to Cape Perpetua, and finish at Fern Canyon in far northern California.

Pack waterproof shoes, a rain shell, and a plan for a slow pace, because the whole point is to stop and stare. Which of the three would you walk first?

Trip tips: grab a rental car to get out here, lock in your hotel before the good rooms are gone, or skip both and book a camper van instead.
