Parking is available at the trailhead, which is located at the former Dosewallips River Road closure. Since the road is decommissioned, you'll park at the end of the drivable section and begin your hike from there.
The initial sections of the trail, especially the first 6.5 miles to the former Dosewallips Campground, are relatively flat and wide, making them suitable for beginners and families. However, the terrain becomes gradually steeper and more challenging further along, particularly if you extend your hike deeper into Olympic National Park.
The trail primarily follows an old, decommissioned road, so it's generally wide and graded. While the first mile is relatively flat, it becomes steeper as you progress, with some sections gaining significant elevation. You'll encounter numerous stream crossings with large cobbles and a major washout about a mile from the trailhead, which often requires navigating by the river's edge or using a bypass trail.
You'll experience lush montane forests, ancient trees, and areas reminiscent of Olympic rainforest valleys. The shimmering Dosewallips River is a constant companion, and further along, you'll get views of snow-capped Olympic peaks. The trail also passes through an area affected by the 2009 Constance fire, offering unique views. Don't miss the Dosewallips River Road itself, and the historic Dosewallips Campground.
The trail offers opportunities to spot various wildlife. Elk are commonly seen in the area, and you might also hear or see owls. Keep an eye out for other forest creatures as you explore the diverse habitats along the river.
As this trail is located within Olympic National Park, dogs are generally not permitted on most park trails. However, dogs are allowed on the Dosewallips River Road itself, which forms the entirety of this route. They must be kept on a leash at all times. Always check the latest National Park Service regulations before your visit.
Yes, the Dosewallips River Road Trail is located within Olympic National Park, so an entrance fee is required. You can purchase a pass at park entrance stations or online. If you plan to backpack overnight beyond the former campground, a wilderness permit is also necessary. For the most current information on fees and permits, please visit the official NPS website: nps.gov.
The trail is generally accessible for hiking from late spring through early fall. During these months, you'll experience pleasant weather and lush scenery. Winter conditions can bring snow and ice, making some sections more challenging or impassable, especially further into the park.
Yes, the route primarily follows the Dosewallips River Road. As you venture deeper, it serves as a gateway to other trails within Olympic National Park, such as sections of the Lake Constance Route and the Tunnel Creek Trail #841, which lead to more remote wilderness areas.
A unique aspect of this trail is its history as a decommissioned road, which means it's wide and gently graded for much of its length, making it popular for both hiking and biking up to the former campground. An insider tip is to be prepared for the major washout about a mile in; navigating it might involve walking along the river's edge if water levels are low, or using a bypass trail with switchbacks. The moss-covered picnic tables and old road signs at the former campgrounds offer a glimpse into the area's past.
The trailhead itself is quite remote, with no immediate amenities like cafes or shops. It's best to come prepared with all necessary supplies, including food, water, and appropriate gear. The nearest towns with services would be outside the immediate park area.
