Course overview

Certified with SSI or any recognised agency? Fun dives on Koh Lanta drop you straight onto Thailand's standout big-fish drift sites with a local guide and no coursework. A typical day combines the deep pinnacles of Hin Daeng and Hin Muang, alive with manta rays and pelagics, with gentler reefs at Koh Haa or Koh Bida. You simply log great dives at your level while the guide handles the currents and logistics.
