Twins Pinnacles – Koh Tao most popular dive site

Twins is possibly the most popular dive site on Koh Tao and if there was a dive site designed specifically for recreational scuba diving to conduct the range of PADI training courses at, then this is the perfect location.

Twins is actually three pinnacles, two large collections of boulders with corals growing on them and a smaller deeper group of rocks a little further west.

We are not certain if the dive site got its name from the two main rock pinnacles underwater or from the two peaks of Koh Nang Yuan island, which overlook this wonderful dive site.

Easy to Navigate at Twins Pinnacles

Twins Pinnacles is an easy dive site to navigate with all three peaks running along an east – west axis.

A perfect dive would be to explore the much smaller deeper peak first and you will find a large adult Longface Emperor fish circling and inquisitive.

Look carefully in the cracks of the rock and you will see Pipefish and Yellow Boxfish, then navigate east to the middle peak.

Diverse Marine Life

The middle peak at Twins has a lot to keep your attention including an archway – (mistakenly referred to as a swim through) – on the north of the site suitable for divers that are confident with their buoyancy.

If divers are not confident with buoyancy here, then we politely suggest you are too far south and Buoyancy World is only a short swim across the sand and is specifically designed for novice divers wanting to improve their buoyancy.

Swim across the middle peak and you will encounter an Anemone fish in their Anemones, various reef fish and several different species of Wrasse, Groupers, Parrotfish and Bannerfish.

You will find Moray Eels hiding in holes and Trevally swimming in small groups or often solitary on the lookout for a quick easy meal.
