Hin Daeng & Hin Muang Diving From Koh Lanta: Tour Prices & Guide
Hin Daeng and Hin Muang: remote pinnacles in the Andaman Sea
Hin Daeng and Hin Muang are two of Thailand's most famous dive sites. Koh Lanta is the closest base to reach them. These remote underwater pinnacles rise from deep water far out in the Andaman Sea, covered in red and purple soft corals.

Do you need advanced certification?
Hin Daeng: be ready for safety stops in open water
Each shop has its own rules:
| Dive shop | Requirement |
|---|---|
| Dive and Relax | Minimum Open Water Diver, but rated for experienced divers only |
| Phoenix Divers | Open Water divers with fewer than 50 dives must add a Deep Dive Adventure for ฿1,000. Divers with over 50 dives can join without advanced certification |
| Blue Planet Divers | Certified to at least 30 m, with your last dive within 6 months. A Deep Adventure dive to 30 m costs ฿900 if needed |
You should be comfortable making a safety stop in open water with no wall or line to hold, since currents can be strong.
