Certified in 1981 this is North Dakota's only nationally recognized canoe trail and is located on the J. Clark Salyer National Wildlife Refuge. The Souris (or Mouse) River flows north here into Canada. A 5-mile route (2 to 3 hours) or a 13-mile route (5 to 7 hours) can be taken. The trail is well marked with mile markers and 3 access points along the river. There are also foot trails, interpretive displays and a visitor contact station at the Refuge Headquarters.
