Bogachiel River Trail to Five Mile Camp

If you’re after classic Olympic rainforest without the crowds, this stretch of the Bogachiel delivers. It’s a lush, low-elevation river walk through moss-draped spruce, hemlock, and cedar, with ferns and skunk cabbage filling the understory. Plan on 12 miles round trip (about 6 miles one way) to Five Mile Camp, with roughly 400 feet of total gain—more stamina than climbing.

You’ll start from the Bogachiel Rain Forest River Trailhead, descending into the river valley and entering Olympic National Park about 1.5 miles in. From there, the path meanders near the Bogachiel River with frequent access to gravel bars and side channels. Expect some muddy, rooty sections and occasional log bridges; a notable crossing is Kahkwa Creek. The river is the star here—broad views of gravel bars, rushing water, and the kind of deep-green quiet you came for.

This hike is best for people who love the feel of a living river corridor more than big views. The forest is dense, and mountain vistas are basically nonexistent. The payoff is a peaceful, primitive camp beside the river and a trail that thins out after the first mile. If you’re curious early on, add the short Ira Spring Wetland Loop near the start before committing deeper into the park.

Wildlife is very much a possibility—elk and black bears roam these valleys—so give animals space and keep your food secured. Water is easy to find in the river and creeks, but treat it.

Tips: Waterproof boots are smart; this trail holds mud year-round and can be slick after rain. The Bogachiel shifts its course, so tread can be rerouted or rough in spots; beyond Five Mile Camp, maintenance drops off. Dogs are allowed only on the first 1.5 miles (before the park boundary), then prohibited—plan accordingly. Vault toilets are at the trailhead; there’s no potable water and typically no parking fee. Day hikers don’t need a permit, but overnight camping in the park (including Five Mile) requires an Olympic National Park wilderness permit.

Best time to hike: Late spring through early fall for firmer tread, long daylight, and wildflowers. This valley is wet year-round, and winter storms can bring blowdowns, flooding, and washouts. For a quieter experience, go midweek and start early; you’ll leave the casual crowd behind within a mile.
