Some of the best-groomed mountain bike trails can be found at Iron Mountain on the south shore of DeGray Lake just outside of Arkadelphia. With more than 24 miles to cover, you would be hard pressed to find better riding anywhere in the state.
From the intersection at Hwy. 64 and Hwy. 155, it's about three miles of rolling hills and one wall of work between you and the top of Mount Nebo. Rising 1,350 feet, it's a very challenging ascent with several sharp switchbacks.
