Three Forks Trail - Three Forks Camp - 8.4 Miles Round-Trip

The Three Forks Trail is easily accessible from the Deer Park Campground and Trailhead in Olympic National Park.

The trail provides access into the lower riparian river valleys of Cameron Creek, the Gray Wolf River and Grand Creek - comprising the 'three forks'.

Leaving from the Deer Park Trailhead (0.0 miles : 5,300'), the trail heads east on the Deer Ridge Trail before quickly connecting with the Three Forks Trail (.25 miles : 5,350'). Views along this quarter-mile stretch are sweeping. Blue Mountain towers to the north with the greater Olympic Range rising to the south.

At the split, turn right (south) onto the Three Forks Trail and the path narrows as it begins a gentle descent through a wide burn area. Views emerge of Mt Deception, Mt Walkinshaw and the Gray Wolf Range as the trail leaves the exposed fire scar and enters a young Douglas fir forest (.5 miles: 5,250').

Now switchbacking south on an aggressive descent, the trail remains virtually unchanged as it works its way through the forest (2.0 miles: 4,050'). Salal and oregon grape carpet the forest understory while Douglas fir dominates the canopy.

At 2.7 miles, the trail sees its first signs on water, joining up briefly with a small mineral stream before breaking away and continuing its descent into the Gray Wolf Valley.

After the continuous switchbacking descent, the trail eventually reaches the bottom of the valley and rolls into Three Forks Camp (4,2 miles : 2,100'). Aside from the various established backcountry sites, the available Three Forks Shelter is a large sturdy 3-walled shelter complete with bear wires and sleping racks. A privy is located behind the shelter.

For those wishing to explore further, follow the signs across two consecutive bridges which lead another .3 miles to Gray Wolf Camp (4.5 miles : 2,050').

The additional stretch passes by the confluence of Grand Creek into Cameron Creek and ends at the confluence of Cameron Creek and the Gray Wolf River.
