Scenic Dosewallips Road (Forest Road 2610) heads west from Brinnon , following the Dosewallips River into the heart of the Olympics and ending 15 miles later at Dosewallips Campground within Olympic National Park .
Sadly, though, the road is washed out at mile 9.2 and may remain so for some time due to environmental concerns. Look for elk along the way.
Approximately three miles up is Rocky Brook Falls. The turnoff isn’t marked, but look for the bridge and small hydro plant on the right side. It’s a short walk to the 80-foot falls, but use care since water levels can change quickly.
The Forest Service’s Elkhorn Campground (free, open May–Sept.) features sites right along the river approximately three-quarters of a mile past the washout on Dosewallips Road. Vault toilets are the rule here.
Dosewallips Falls cascades over enormous boulders just inside the Olympic National Park  boundary, about four miles past Elkhorn along the road-turned-trail. Just another mile farther is the National Park Service’s Dosewallips Campground (www.nps.gov/olym , free, no reservations), a primitive site with no water and pit toilets.
A trailhead here provides access to the park backcountry via the West Fork and Main Fork Dosewallips trails. The site is not to be confused with the easier-access Dosewallips State Park .
