You step off the long-tail boat and the sea sighs behind you, pushing the shoreline a little closer to the limestone cliffs. Ahead, a short fishing village gives way to a steep natural trail that angles up through scrub and the thick scent of salt and pandan. The trail climbs roughly 430 meters of uneven, jungle-cut steps and rock before a narrow entrance spills you into Phraya Nakhon Cave.
