Plan your hike

Before you go

Parking

Start at Bogachiel Rain Forest River Trailhead at the end of Undi Road southeast of Forks. The trailhead has ample parking, an information board and a vault toilet. The final primitive-road section is rough; all-wheel drive or four-wheel drive is best. The river route follows the lower Bogachiel Rain Forest Trail for about 1.5 miles before reaching the park boundary.

Safety

This is a remote multi-day route with multiple creek crossings, exposed eroded-bank sections and difficult route-finding above 15-Mile. Creeks can be ankle- to knee-deep and unsafe or impassable in high water. Overnight trips require wilderness permits and reservations; bear canisters are required for food, garbage and scented items in the Mink Lake area. There are no toilets on the route, and all water must be treated. Dogs are prohibited inside Olympic National Park.

Trail guide

Hiking Bogachiel River Trail

A multi-day river-valley routeThe Bogachiel River Trail is a 48.

The Bogachiel River Trail is a 48.8-mile out-and-back from Bogachiel Rain Forest River Trailhead to the Mink Lake Trail junction. The selected mileage is 24.4 miles each way from the trailhead, including roughly 1.5 miles on the lower approach before the park boundary. A separate park trail-conditions table lists 21.6 miles from the boundary, so published figures do not line up exactly; use 24.4 miles each way as the planning figure, not an averaged distance. The route ends at the junction, not at Mink Lake, which is farther along another trail. This is a multi-day wilderness trip, not a long day hike; plan on several days for the rough tread and repeated crossings.

Start on the lower rainforest trailThe shared trailhead also serves short loop hikes, but those are different outings.

The shared trailhead also serves short loop hikes, but those are different outings. For the river route, descend through spruce and alder to the valley floor, then stay with the main trail as it follows an old road grade through mossy alders and sword fern. The approach is about 1.5 miles to the park boundary. Expect wet, muddy footing in this lowland forest, especially around the creeks.

Follow the river, not the bankOnce inside the park, the trail keeps to the rainforest valley, with spruce, hemlock, cedar,…

Once inside the park, the trail keeps to the rainforest valley, with spruce, hemlock, cedar, ferns and hanging moss. Riverbank erosion has forced sections away from the water and onto higher ground. At one exposed cut bank, the route climbs above the river before dropping toward Mosquito Creek. The trail is low-maintenance, and its tread becomes rougher and less distinct farther in.

Crossings and the upper valleySeveral creeks cross the route.

Several creeks cross the route. They can be ankle- to knee-deep and may become unsafe or impossible during high water, so this hike can turn around on river conditions even when the trail itself is passable. Above the 15-Mile area, the route is harder to follow. It also climbs out of the low river corridor toward the Mink Lake and Little Divide junction, finishing around 4,130 feet. The mileage and route-finding make a map and a careful backcountry plan essential.

Broad gravel bars open beside the river at Bogi Camp, one of the few places where the forest briefly gives way to a wider river view. Around six miles in, the old Snider-Jackson junction marks the former Bogachiel Ranger Station, shelter and horse stable. A 1989 flood swept those structures away along with many large trees. Bogachiel is often translated as “muddy waters,” which fits both the river valley and the trail’s damp character.

Overnight travel requires a wilderness permit and reservations under the park’s backcountry rules. Bear canisters are required for food, garbage and scented items in the Mink Lake area. There are no toilets along the wilderness route; treat water from the river or side streams. Dogs are prohibited on the park portion, so pets cannot accompany you on this full route. The trailhead has a vault toilet and ample parking, but the last stretch of access road is primitive; a higher-clearance, all-wheel-drive or four-wheel-drive vehicle is the safer choice.
