From the trailhead across the road from the parking area, ride one-tenth of a mile down Third Flats Road to get to the start of the Twist-N-Shout trail. After descending approximately 400 feet during about 2.3 miles of twists & turns, the start of Butterknife appears. This is a 6.3 mile singletrack ride that will descend the whole way for another 600 to 800 feet. After reaching the end of the Butterknife at an elevation of approximately 4900 feet, the 1000 to 1200 feet of elevation must be re-gained over 3.9 miles via a jeep road (Third Flats Road). That makes the total distance approximately 12.6 miles. The 3.9 miles of jeep road is a lung buster. to eliminate the jeep road you can drive a well equipped 4 wheel drive to the end of Butterknife. There is no water at the trail head so a minimum of 100 oz or more is needed for this ride.
