Hall of mosses

Hoh River Trail

General Description

The Hoh Rainforest is the most famous temperate rainforest in the world. Designated a UNESCO Biosphere Reserve and World Heritage Site, it receives over 140 inches of rain a year and is filled with spectacular old growth trees.  With ancient trees and deep cushions of moss, it is a prehistoric wonderland. The rainforests of Olympic National Park contain the highest biomass of anywhere in the world thanks to the prolific rainfall and summer fog. And due to all that moss the Hoh is one of the quietest places on earth. So come for the solitude and the incredible trees, but stay for the diversity of wildlife, the ferns and shrubs of the understory, and the glacial waters of the Hoh River. There are plenty of stunning destinations available for hikers of all levels, from a slow amble through the Hall of Mosses to a long backpacking trip up to the Blue Glacier on Mt. Olympus.

Getting to the Hoh River Trailhead

From Highway 101, turn East onto Upper Hoh Rd and follow it 18 miles to the Hoh Rainforest Visitor Center.

History of the Hoh Rainforest

The Hoh Rainforest is a unique ecosystem, filled with endemic plants found nowhere else in the world, thanks to six periods of glaciation that separated in from the mainland. The indigenous peoples of the Olympic Peninsula have visited the Hoh River for thousands of years, accessing a treasure trove of salmon runs and plant life. While much of the old-growth rainforest of the Olympic Peninsula was logged during the 20th century, citizen pressure and the formation of Olympic National Park protected the Hoh Rainforest, preserving it as a unique ecosystem and critical wildlife habitat. Classic National Park architecture buildings can be found along the trail, from the Olympus Guard Station to the Happy Four Shelter (built by 4 foresters who, according to local legend, hated one another and were the opposite of happy).

3 Best Day Hikes in the Hoh Rainforest

Take a short stroll among the Hall of Mosses, or head all the way for the Blue Glacier and Mt. Olympus.

Below are the primary options for day hiking in the Hoh Rainforest

Destination Miles Elev Difficulty Style
Hall of Mosses 0.8 mi 100 ft Easy Loop
Mineral Creek Falls 5.6 mi 100 ft Easy Out and Back
Five Mile Island 10 mi 300 ft Moderate

1. Hall of Mosses

The Hall of Mosses is an easy interpretive trail that’s perfect for families, stretching your legs, and learning about the ecosystem of the Hoh Rainforest. At less than a mile long, it’s ideal for photography and for slow appreciation of the giant trees and thickly layered moss. Keep an eye out for licorice ferns epiphytes, and shrubs growing high in the canopy of the Bigleaf Maples. When you’re done, return to the visitor center for more interpretive exhibits.

2. Mineral Creek Falls

Mineral Creek Falls is a pleasant out and back hike that takes you deeper into the rainforest. Follow the Hoh River Trail past giant Sitka Spruces and under towering Bigleaf Maples, and keep an eye out for trees and shrubs growing out of nurse logs–old fallen trees that provide nutrients and a stable platform for new trees to take root. A short side spur at 0.9 miles leads to a gravelly beach on the Hoh River. Continuing along the main trail eventually brings you to a bridge over Mineral Creek, and to a small but beautiful waterfall. Stop here for photos and lunch, or continue just a little further to Mt. Tom Creek, where you can enjoy lunch alongside the river before returning to your car.

3. Five Mile Island

Five Mile Island is a great all day hike. Follow the Hoh River Trail as above, but continue past Mineral Creek and further into the forest. The further you go, the fewer people you’ll see, and the quiet of the Hoh Rainforest will truly begin to set in. Keep an eye out for elk, black bear, deer, and more as you hike through the ancient forest. Upon reaching Five Mile Island the forest will open up into a beautiful series of maple flats, and you can head to the river for views of Bogachiel Peak and the gravelly braids of the Hoh River. Five Mile Island is a perfect lunch spot and a great spot for a nap. Return the way you came to round out the hike.

2 Hoh River Trail Backpacking Trips

The Hoh River is a wonderful backpacking destination, with options for easy kid-friendly trips as well as longer trips that lead up into the mountains and high alpine meadows.

Route Miles Difficulty Campgrounds
Five Mile Island 10 mi Easy Five Mile Island CG
Blue Glacier 37 mi Strenuous Olympus Guard CG
Elk Lake CG
Five Mile Island CG

1. Five Mile Island (2 days)

Five Mile Island is a great destination for kids, a first time backpacking trip, or a relaxing overnight for the more experienced hiker just looking to get out for a spell. Majestic old growth trees line the well-maintained trail, while forest flowers and fallen epiphytes decorate the ground. The gravelly banks of the Hoh River at Five Mile Island are the perfect spot to enjoy an evening fire and watch the light change on Bogachiel Peak, and there are ample trees to hang up a hammock and relax after a pleasant hike. Make sure to bring bear canisters  to keep your food safe, and warm clothes for the evening.

2. Blue Glacier (5 days)

This 5 day trip takes you all the way to the end of the Hoh River Trail and an overlook of the Blue Glacier from a moraine high above. While the first day stays relatively level, winding through an ever-changing mosaic of old-growth forest, the next days have plenty of elevation gain to compensate. Eventually the trail leaves behind the river floor and climbs up through giant Douglas Firs and over a dramatic bridge suspended high above the Hoh River. Two nights at Elk Lake provide a chance to go for a swim, watch for wildlife, and take a dayhike up to the Blue Glacier on Mt. Olympus. Stare into the deep blue crevasses, look for the tiny dots of climbing parties attempting to summit the peak, and enjoy the delicate alpine wildflowers that dot the moraine. Make sure to taste the huckleberries above treeline–they’re the sweetest and most flavorful berries you can find. A steep rope ladder down an avalanche chute provides an element of excitement, but it’s nothing that a little concentration and nerves of steel can’t handle. Hiking the Hoh River Trail all the way to its end and back gives you a great taste of the diversity of Olympic National Park. To finish off the trip, head back down and camp at Five Mile Island for one last night, or hike all the way out from Elk Lake if you’re feeling strong or in a rush.

When to Hike and Seasonal Considerations

Olympic National Park has a reputation for rain, but summers tend to be dry, warm, and very pleasant. Enchanted Valley is a rare low-elevation destination that can be hiked as early as May without having to worry about too much snow, but if you’re hoping to cross the passes or day hike into the high country, you’ll want to wait until late June or July. The waterfalls are most dramatic in early summer, but abundant berries and fall colors in August and September make it a spectacular location all summer long. Make sure to check the weather before you plan your trip.
