This updated guide (new 5th edition - published May 2016) contains ten maps, elevation profiles and complete walking descriptions of this 223-mile trail - the longest hiking trail in the region (it runs from Talimena State Park in Oklahoma to Pinnacle Mountain State Park near Little Rock). It contains all the information that you need to have a safe and enjoyable hike. The Ouachita Trail has been improving over the years, and Tim Ernst details all of it, including the new trail shelters that have been built. It also pinpoints, on the maps and in the text, all of the reliable water sources along the trail, which are of extreme importance. The foreword was written by Ouachita Trail guru and famed outdoorsman Jim Rawlins. This guidebook is a must for anyone hiking the Ouachita Trail-don't hit the trail without it! This guidebook was produced in cooperation with the Friends of The Ouachita Trail (FoOT) and the U.S. Forest Service.
