Course overview

Already certified? Fun dives on Koh Lanta put you straight onto Thailand's best big-fish drift sites with no coursework, just guided diving. A typical day-trip combines the deep pinnacles of Hin Daeng and Hin Muang, where manta rays and pelagics patrol soft-coral walls, with calmer reefs at Koh Haa or Koh Bida. You dive at your own level under the eye of a local guide who knows the currents and the seasons.

• Read and dive comfortably in mild-to-moderate currents

Prerequisites
