Why the Hoh Rain Forest Is Worth the Drive
The Hoh Rain Forest sits on the west side of Olympic National Park, fed by roughly twelve to fourteen feet of rain a year. That moisture grows some of the most dramatic temperate rain forest in the country: Sitka spruce and western hemlock draped in club moss, ferns carpeting the ground, and nurse logs sprouting whole rows of young trees. The Hoh Visitor Center is the trailhead hub, reached by an 18-mile spur road off US-101 near Forks. Plan for a long drive in, because the road dead-ends here and there is no quick loop back out. This is one of the headline stops on the Olympic Peninsula family road trip, and the short loops near the visitor center are flat enough for nearly anyone.
Hall of Mosses Trail
The Hall of Mosses is the trail everyone comes for. It is a 0.8-mile loop with only about 100 feet of gentle climb, and it starts right behind the Hoh Visitor Center. The path winds under big-leaf maples so heavily hung with moss that the light turns green. Go slowly and look for the small grove of maples about a third of the way in, where the moss curtains are thickest. Early morning light filtering through the canopy is the photographer's reward, and the parking lot is far emptier before 9 a.m.
Key facts for the Hall of Mosses:
- Distance: 0.8 miles, loop
- Elevation gain: about 100 feet
- Surface: packed dirt with a few stairs; not fully stroller friendly
- Time: 30 to 45 minutes at an easy pace
Spruce Nature Trail
If the Hall of Mosses leaves you wanting more, the Spruce Nature Trail starts from the same trailhead area and runs 1.2 miles. It is even flatter and follows a stretch of the Hoh River, with interpretive signs explaining how the river reshapes the forest. You will pass towering Sitka spruce and gravel river bars where elk often graze at dawn and dusk. Combine both loops for a relaxed two-mile morning before the crowds build.
Hoh River Trail for Longer Days
For hikers who want distance, the Hoh River Trail heads deep into the backcountry toward Blue Glacier and Mount Olympus. The good news for day hikers is that the first several miles are almost dead flat. A turnaround at Mineral Creek Falls is about 5.4 miles round trip, and Five Mile Island is around 10.6 miles round trip. You hike under continuous old-growth canopy the whole way, so even a short out-and-back feels remote. Carry the ten essentials, because cell service ends well before the trailhead and weather changes fast.
Wildlife and What to Watch For
The Hoh is home to Roosevelt elk, the largest elk in North America, and the forest you are walking through is partly shaped by their grazing. You may also see black-tailed deer, banana slugs the size of a finger, and dozens of bird species. Keep a respectful distance from elk, especially cows with calves in late spring. Mosquitoes can be thick in summer near the river, so pack repellent.
Best Time to Visit and Practical Tips
The rain forest is open year-round, but conditions vary a lot by season:
- Summer (July to September): driest months, busiest parking, best for the Hoh River Trail
- Spring and fall: lush, fewer people, more rain and richer green color
- Winter: quiet and atmospheric, but heavy rain and occasional road closures
Parking at the Hoh Visitor Center fills by mid-morning in summer, and there is no overflow lot for miles. Arrive early or in the late afternoon. There is an entrance fee for Olympic National Park, and rangers staff a station on the Hoh Road. Bring layers and a rain shell no matter the forecast, because this is a rain forest and a dry day is never guaranteed. If you are stitching this into a wider trip, the 7-day Olympic loop pairs the Hoh with the coast and Hurricane Ridge for a full cross-section of the park.
