About this spot
Hin Daeng and Hin Muang are twin underwater pinnacles rising from deep water off the Phang Nga coast. These seamounts attract experienced divers seeking exposure to open-ocean conditions and large pelagic species. The dive sites demand solid buoyancy control and current awareness; depths range from 12m at the shallows to 50m on the deeper walls, making them unsuitable for novices. These pinnacles are fed by nutrient-rich currents that support prolific marine life. The granite formations create dramatic underwater topography with crevices and overhangs. Because the sites sit away from shore, they draw fewer casual visitors and retain a raw, pristine character. Boat access is essential; most trips launch from Krabi or Phuket. Conditions vary with season, though diving is viable year-round. Currents can run strong, especially during the cooler months, so pre-dive briefings emphasizing drift protocols are standard. The reward is close encounters with sharks, rays, and large schools of jacks and snapper. Night dives here are uncommon but spectacular for those equipped to handle deeper, current-swept terrain. No special permits are required, and the sites remain outside marine protected areas, making them accessible to commercial dive operators. However, you must book through an established outfit with experience in deep, current-exposed diving. These are not shore dives or beginner destinations.

Preguntas frecuentes
›When is the best time to dive Hin Daeng and Hin Muang?
Year-round diving is possible at these sites. Currents tend to be stronger during cooler months (roughly November–February), which can create more challenging conditions but also concentrate marine life. Summer months are calmer, making them better for divers new to these pinnacles. Check with your operator for current forecasts before booking.
›What depth range and difficulty should I expect?
Depths run from 12m to 50m, placing these firmly in the advanced category. Strong currents are common, buoyancy control is critical, and you must be comfortable navigating open-water conditions. Only certified advanced divers should attempt these pinnacles. Shallow sections (12–20m) are less demanding but still require current awareness.
›What marine life will I see?
The nutrient-rich waters surrounding these pinnacles support sharks, rays, groupers, large jacks, snapper schools, and other pelagic fish. Sightings vary by season and current, but the exposed location and depth range mean you're more likely to encounter big animals here than at sheltered reef sites.
›How do I access these sites and do I need permits?
Both pinnacles lie outside marine protected areas and require no special permits. All access is by boat, typically through dive operators based in Krabi or Phuket. Trips are strictly commercial; no independent diving is practical. Book with a shop experienced in advanced pinnacle diving.
