Southwest of Billings and northwest of Red Lodge in the Custer National Forest, the Benbow Mine Trail system is open to ATV riding. The trail system consists of forest service roads and rough jeep trails. A loop can be formed by linking these roads. There is also a one-way route out Nye Basin that is worth exploring.
