The Tennessee Pass Nordic Center is located near the base lodge at Ski Cooper - just on the other side of the parking lot. The nordic center has a large selection of rental equipment and also a snack bar to replenish yourself.
Available rental equipment includes track skis, skate skis, telemark skis, snowshoes, and kids sleds. Prices range from $8 - $20 for rentals.
