Hin Wong Pinnacle dive site, Koh Tao, is The Divers Boat’s secret weapon when the weather turns. Tucked on the east coast of Thailand’s diving island, sheltered from the prevailing westerly winds. This site stays accessible when conditions shut down the west coast entirely. Majestic sea fans, giant groupers, nudibranchs and filefish. Hin Wong Pinnacle is far more than a weather backup. It is a destination in its own right, consistently rewarding for certified divers who take time to look closely.

Hin Wong Pinnacle dive site Koh Tao: the east coast advantage

Hin Wong Pinnacle sits on the east coast of Koh Tao, on the opposite side of the island from the big offshore sites like Chumphon Pinnacle or Sail Rock. Thanks to this position, sheltered from the prevailing westerly winds, it is one of the very few sites on Thailand’s diving island that remains accessible in virtually any weather conditions. When conditions shut down the west coast, Hin Wong Pinnacle becomes our destination of choice and more often than not, the highlight of the day.

The journey from Mae Haad takes approximately 40 minutes by boat, rounding the island. However, when the boat is moored on the east side. The site is just 10 minutes away a significant advantage in rough weather. Furthermore, the east coast of Koh Tao sees far less boat traffic than the west: fewer boats, fewer divers in the water, undisturbed marine life and altogether more peaceful dives.

The sea fans of Hin Wong Pinnacle — the signature of the site

What sets Hin Wong Pinnacle apart from other Koh Tao dive sites is above all its gorgonian sea fans. These fan-shaped corals, ranging in colour from bright yellow to deep orange, cover the walls of the pinnacle from around 15 metres down. Anchored in the current, they filter suspended particles and shelter a remarkable micro-fauna: shrimps, small fish and nudibranchs that only the most patient divers manage to spot.

Moreover, the rocky walls of Hin Wong Pinnacle drop progressively to 30 metres. It’s offering a varied dive profile suitable for both Open Water certified divers and Advanced divers looking to explore the deeper sections. It is precisely this versatility that makes the site a consistently worthwhile destination whatever the conditions.

Marine life at Hin Wong Pinnacle Koh Tao: what you’ll encounter

Hin Wong Pinnacle is a macro and observation site at heart, where every dive rewards those who slow down and look carefully. The marine life here is discreet but varied — and it is precisely that quality which makes the site so endearing to divers who know it well.

What level do you need to dive Hin Wong Pinnacle Koh Tao?

Hin Wong Pinnacle is accessible to divers holding a minimum Open Water (OW) certification. The top of the pinnacle at 10 metres is well within OW limits and already hosts interesting marine life. However, to reach the most impressive sea fans and explore the walls down to 30 metres, an Advanced Open Water (AOW) certification is recommended.

Furthermore, the macro richness of Hin Wong Pinnacle makes it an excellent setting for the Underwater Photography SSI specialty — the sea fans and nudibranchs provide exceptional photographic subjects in a calm, sheltered environment. Talk to The Divers Boat team to combine a specialty with your fun dive day.
