South Fork Hoh River Trail - 8.0 Miles Round-Trip

The South Fork of the Hoh River is formed by Hubert Glacier on the south flank of Mount Olympus, and flows west into the main stem of the Hoh River near the Olympic National Park Boundary.

The South Fork Hoh River Trail begins just upstream of the confluence and runs 4 miles through intervals of forest, meadow and open river banks before fading out along a sharp bend in the valley.

While the Hoh River Trail is among the Park's most popular hiking and backpacking corridors, the nearby South Fork sees a fraction of the traffic and offers genuine solitude in a pristine old-growth rainforest:

The trail drops from the trailhead and abuts a forest service road before leveling out to the Olympic National Park Boundary. NPS travel and camping rules apply beyond this point (.5 miles : 735').

Trees are noticeably larger and the understory is much thicker once inside the Park. The trail crosses a major tributary (1.0 miles : 765') leading to Big Flat (1.4 miles : 690'), a wide point in the valley with level grades, river access and sunny meadows ideal for backcountry camping.

The trail passes Big Flat to your first clear (albeit brief) view of the South Fork (2.0 miles : 725'). It quickly edges away under a massive canopy of Douglas Fir, Western Hemlock and Cedar broken by small glades (2.5 miles : 755').

The forest gradually opens to large meadows with several excellent campsites as you head upstream (3.0 miles : 765'). The trail meets a bend in the river against the north valley wall with a nice look at Hoh Peak (3.5 miles : 785').

It closely follows the river now and eventually becomes squeezed between it and the steep valley wall. This well-defined path gradually fades amid forest debris and downfall to the end of the maintained trail (4.0 miles : 810'). 

Views from the end of the trail are terrific. Hoh Peak (5,570') looms in the distance, and interesting gravel bars can be accessed during periods of low river flow. Travel past the 4.0 mile mark, while technically possible, is not recommended due to hazardous conditions.

Worth Noting

  • Expect muddy trail conditions, even during dry periods. There are several creek crossings on fallen logs that may be uncomfortable for some when wet, or with heavy packs. Alternatively, these crossings are easy-moderate fords.
  • Despite proximity, river access is somewhat limited along the trail. Campsite access spurs offer reliable paths to the river.
  • Don't Tread on Redd! A redd is an 8' x 4 ' depression (nest) in the river constructed by female salmon to deposit their eggs. Fisheries biologists and the Hoh Indian Nation are concerned about the trampling of these Chinook salmon and Steelhead trout nests so please do not wade in nest areas or disturb spawning fish.
  • The Hoh Rainforest receives up to 145" of rain per year.
  • The South Fork of the Hoh River sees much less traffic than the main Hoh River making it a haven for park wildlife including black bear, mountain lion and Roosevelt elk.
  • A lightning strike on July 26, 1978 in the Hoh River Valley became the largest fire in Olympic National Park history. After smoldering for 12 days, the fire ignited on August 7 and burned 1050 acres in just two days. Rain on August 10 extinguished much of the fire, though individual trees burned for several months.

Where bear canisters are not required, they are strongly recommended.

Fishing Information

"This has to be the nicest trail you've never heard about on the Olympic Peninsula. I was told about it by a friend who has been fishing the west side rivers for many years. He said this is an amazing bit of rainforest with massive trees and flat terrain - exactly what my family was looking for in a weekend adventure. The trailhead is remote and takes some time to reach, but it's worth the extra drive. The only caution I'd mention is the potential for fallen trees across the road - you definitely don't want to get stuck because phones won't work and it would be a long time before anyone comes by to help. Otherwise the road is in surprisingly good shape, especially for winter. I look forward to coming back this spring to camp with the kids."
