notes

• This is great as both a day hike for any portion of the road/trail or as an easy weekend backpacking or bikepacking trip.
• For those with extra energy, the nature trail  loop at the camp is a nice addition.
• For those wanting a workout, the Lake Constance Trailhead is 5 miles from the road washout/trailhead at 1,400 ft. It's 2.2 miles one-way and 3,300 feet of elevation gain.
• The Land Manager for the trailhead is the National Forest Service. No parking permit is required, as the trailhead is just the blocked off road and there are no services available. The road/trail does enter the Olympic National Park a few miles in, but does not require a National Park Entrance Fee. Camping at the abandoned Dosewallips Campground does not require fee or wilderness permit, because it's officially still a car campground. Past the campground, camping does require a wilderness permit.
