Certified in 1976 as a National Recreation Trail the Old Oak became North Dakota's first nationally recognized trail and is located at Lake Metigoshe State Park. The 3-mile nature trail winds through the aspen, birch and oak forests of the Turtle Mountains along the Canada-US border. Interpretive markers are place along the trail with a corresponding brochure to identify natural wonders. The trail can be used for hiking, biking, snow shoeing and cross country skiing.
NOTE: an NRT Trail Ambassador walked this trail on 5/28/2018 and reports that the second half of the loop has several trees across the trail.
