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.
There's a reason it's called the Jasper Disaster. Mile for mile, this Ozark route is one of the most difficult in the state, with some 316 turns in 56 miles
