Beautiful route into the mountains and then down to the coast of Koh Phangan. First section clockwise is on paved, steep road and then transitions into rugged dirt road terrain. The heat in May should be taken seriously as the route is very exposed and there is little water access the second half of the route. Heat is by far the most challenging aspect of this route so prepare accordingly! Spectacular views along the top with no road or foot traffic along seemingly deserted roads and trails the second half of the route. ~75% of the route is exposed to direct sunlight with ~25% shade provided by the jungle canopy speckled throughout the route. The jungle and scenery is absolutely stunning and we felt very safe along the way. Very easy to follow if you download the gpx file.
