Haad Nam Tok 10.5 km. from the ferry pier
Small, about 50 meters long, Haad Nam Tok beach is considered wild. All that is on it is a canopy and several destroyed houses. Nearby is the abandoned Koh Phangan airport. You can get to the beach either on foot or by bike (if you are confident in your driving experience), but the descent to the beach is steep and the road, if you can call it that, passes over the rocks through the waterfall.
Previously, a concrete road led to this beach, but now it is completely destroyed. All water and food must be taken with you, and be sure to choose suitable shoes for descent and ascent.
