Ancient trees, living moss, and total silence: Washington’s Hoh Rain Forest earns every raindrop

It’s one of America’s last true rainforests

The Olympic Peninsula in Washington has a lot going for it, but nothing quite prepares you for the Hoh Rain Forest.

Twenty-four square miles of old-growth trees, moss-draped maples, and glacier-fed river sit on the western edge of Olympic National Park, soaking up 140 inches of rain every year. Every surface is green.

The fallen trees grow new trees. The quiet here is the kind you can actually feel.

And the deeper you walk, the more the outside world disappears.

Ancient land of the Hoh people and glaciers

Long before the trails and the visitor center, the Hoh River valley was shaped by glaciers that carved it out thousands of years ago.

The Hoh people have called this peninsula home for centuries, and the name itself may trace back to the Quileute word “Ohalet,” meaning fast moving water or snow water.

This forest once stretched in an unbroken band from southeastern Alaska all the way down to central California.

Of the four rainforests on the Olympic Peninsula, the Hoh is the only one designated a UNESCO World Heritage Site and Biosphere Reserve.

Trees so wide it takes five people to wrap their arms around them

The forest canopy here belongs to Sitka spruce and western hemlock, and some of them top 300 feet and stretch 23 feet across at the base.

Coast Douglas fir, western red cedar, bigleaf maple, and black cottonwood fill in around them.

Over 130 species of moss, lichen, and fern live throughout the forest, coating trunks, branches, and the ground in every shade of green.

The moss draping from the trees is an epiphyte, meaning it pulls everything it needs from the air and rain without taking a thing from the tree it grows on.

New trees grow out of the bodies of fallen giants

One of the strangest things you’ll see in the Hoh is what happens after a massive old-growth tree falls. The log doesn’t just rot.

It becomes a platform, dense with nutrients, where new seedlings take hold and send roots down through the decaying wood.

Walk far enough and you’ll find straight rows of young trees standing on arched roots above the ground, the old nurse log long since dissolved beneath them.

It’s the forest’s version of a relay race, running without interruption for thousands of years.

Walk the Hall of Mosses in under an hour

The Hall of Mosses Trail covers 0.8 miles in a loop and takes most people somewhere between 30 minutes and an hour.

The trail passes through old-growth forest before moving into a grove of bigleaf maple trees thick with club moss hanging in curtains from every branch.

It starts from the parking lot near the visitor center, the terrain is easy, and nearly anyone can walk it.

One thing to keep in mind: pets aren’t allowed on this trail, so if you’re bringing a dog, you’ll need to plan around it.

The Spruce Nature Trail runs quiet along the river

If the Hall of Mosses draws a crowd, the Spruce Nature Trail tends to run quieter.

The 1.2-mile loop winds through both old-growth and younger forest, follows Taft Creek, and reaches the bank of the Hoh River, where the water runs a milky, glacial gray-green.

Signs along the way identify trees and plants as you go, so you can put names to what you’re seeing.

The trail is nearly flat the whole way, making it a good option if you have kids or just want an easy walk with a lot to look at.

The Hoh River Trail goes 18.5 miles into the wilderness

For a longer push, the Hoh River Trail runs 18.5 miles one way from the visitor center all the way to the Blue Glacier beneath Mount Olympus, the largest glacier in Olympic National Park.

The first few miles stay flat and move through old-growth forest, so a day hike is absolutely worth it. Most casual hikers turn around at Mineral Creek Falls at 2.7 miles or Five Mile Island at 5 miles.

If you want to go all the way to Glacier Meadows, plan ahead. Overnight trips require a wilderness permit and advance campsite reservations.

Roosevelt elk roam the meadows and riverbanks

Roosevelt elk are the largest of the four North American elk species, and Olympic National Park holds one of the biggest wild herds in the Pacific Northwest.

You’ll often see them grazing near the river and in the open meadows, especially in the early morning.

Black bears, black-tailed deer, river otters, bobcats, and cougars also live here, though the elk are what most visitors come across first. Keep your eyes low on the forest floor too.

The banana slug turns up often, a bright yellow creature that can reach 10 inches and ranks as the second-largest land slug species in the world.

Gordon Hempton called it the quietest spot in America

In 2005, acoustic ecologist Gordon Hempton placed a small red stone on a mossy log about three miles up the Hoh River Trail, marking it as the quietest place in the United States.

The project, called One Square Inch of Silence, set out to draw attention to how fast natural quiet is disappearing across the country. The thick moss absorbs sound.

The remote location keeps human-made noise at a minimum.

If you walk out to that spot and stand still, what you hear is layers of forest: wind in the canopy, the river somewhere below, birds you can’t place.

The forest floor after a good rain is its own world

The canopy of conifers and deciduous trees keeps direct sunlight from reaching the ground, so the forest floor stays cool and damp through most of the year.

After rain, the moss deepens and the greens saturate to something you’d have a hard time describing. Western sword ferns spread across the ground like a continuous carpet.

Lettuce lichen hangs from the branches overhead. Below all of it, fallen wood breaks down fast in the wet conditions, feeding the soil, which feeds the roots, which feeds the trees. Nothing here goes to waste.

Plan the details before you drive out

Upper Hoh Road, the only way to reach the trailheads and visitor center, reopened May 8, 2025, after flood damage closed it in December 2024.

Always check current road conditions on the National Park Service website before you go. Entry costs $30 per vehicle or comes free with a National Park pass.

The visitor center runs daily during summer, closes from January through early March, and operates Friday through Sunday in spring and fall. About 460,000 people visited the Hoh area in 2024, so expect waits of one to two hours at the entrance during peak summer hours between 9 a.m. and 5 p.m.

A forest that rewards anyone willing to slow down

The Hoh has stayed this intact because Olympic National Park has protected it for decades, and that protection shows. Trees fall and new ones grow from them.

The river runs cold and clear off the glacier. The elk move through the meadows on their own schedule.

Whether you walk the easy half-mile loop or pack in for a week, the forest doesn’t change its pace for you. The sounds, the scale, the deep green of everything around you, it all asks you to stop moving for a moment.

Most people who do are glad they listened.

Visit the Hoh Rain Forest in Washington

You can reach the Hoh Rain Forest by taking Upper Hoh Road off Highway 101, about 18 miles in, roughly an hour from Forks and about four and a half hours from Seattle.

Three trails leave from near the visitor center: the Hall of Mosses at 0.8 miles, the Spruce Nature Trail at 1.2 miles, and the Hoh River Trail running up to 18.5 miles one way.

The campground has 72 sites along the river and stays open year-round. Reservations through Recreation.gov are required from June through September.

Pets are welcome on leash at the campground and on the Hoh River Trail, but not on the Hall of Mosses or Spruce Nature Trail.
