Route and access notes

A soil-surface hiking trail linking campgrounds along Sullivan Lake in Washington's Colville National Forest. This assessment covers the connected mapped Sullivan Lake Trail and does not imply that the historical registry details are current.

Planning this route

The connected source is 6.7 km, close to the National Recreation Trails record's 4.3 miles. The record describes an out-and-back backcountry trail between campgrounds. Use a current Forest Service map for navigation and verify seasonal services separately.

Access and source limitations

The National Recreation Trails page explicitly warns that its 1978 application record may be out of date. Contact the Colville National Forest trail manager and check current fire, wildlife, road and campground notices before visiting.
