South Fork Hoh River Trail

Why go

If you want Olympic rainforest magic without the Hoh Rain Forest crowds, this is your move. The South Fork Hoh River Trail is a mellow, moss-draped river walk through towering Sitka spruce, Douglas fir, and bigleaf maple, with frequent river access and a strong chance of seeing elk on the gravel bars. It’s underrated, peaceful, and lush.

The hike

Plan on about 7.0 miles total, out-and-back, with roughly 150–200 feet of rolling gain. The path starts in second-growth forest outside the park, then enters Olympic National Park and quickly feels wilder. Expect classic rainforest tread: roots, mud, and a few unbridged stream crossings via rocks or logs. Around 3.5 miles in, you reach Big Flat—glaciated bottomland with open maple glades and big river bends—before the maintained tread peters out near a slide area with a broad river view.

What you'll see

This is prime temperate rainforest: curtains of moss, carpets of oxalis and fern, and old-growth giants once you’re inside the park. The broad valley and constant moisture fuel the greenery, and the Big Flat’s silted flats and grassy openings make great wildlife-viewing perches. Keep your eyes on the bars for elk and listen for busy birdlife overhead.

Crowd level and tradeoffs

You’ll see far fewer people here than on the main Hoh trails—that’s the point. The tradeoff: a rougher access road, some mud, and no facilities. If you want easy access and interpretive signage, head to the main Hoh corridor instead. If you want quiet rainforest and river time, stay here.

Logistics and tips

• Day hiking requires no permit. For overnight camping (popular at Big Flat), you’ll need a park wilderness permit; carry and use proper food storage (bear canisters recommended where hanging isn’t possible).
• No toilets; bury waste properly and treat all water.
• Pets are not allowed once you enter the national park.
• Footing can be slick on roots and silt; waterproof boots help. After storms, creeks can run higher and the final road stretch can be rutted—check current conditions before you go.

Best time to hike

Year-round is possible, but spring through early summer is peak green, and fall brings great maple color. Winter is beautiful and wet, with frequent rain and potential access issues. For softer light and solitude, start early or aim for weekdays.
