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.
From Mena on the Talimena National Scenic Byway, it's a nine-mile sufferfest up Rich Mountain, the state's second highest peak, and the site of splendid Queen Wilhelmina State Park, Arkansas's Castle in the Clouds.
At 108 miles, the Ouachita National Recreation Trail is the longest mountain bike trail in the state. The ride presents a true adventure trip with beautiful views, steam crossings, and rugged terrain. Expect to do some hike-a-biking on this trail.
