Chumphon Pinnacle

This challenging dive site with strong currents is an exciting dive featuring a huge granite pinnacle and several smaller pinnacles. The rocks are habitat for a variety of marine life, including large creatures such as whale sharks. Barracudas, giant groupers, tuna, batfish, and many other sea creatures can be frequently seen here.

Sail Rock

Sail Rock is a world-renowned dive site located north of Koh Samui. It’s a big granite pinnacle that plunges 30 meters below the surface of the water. The most famous feature is its so-called chimney, a vertical swim-through that can be entered at about 18 meters (60 feet) and exited at 12 or 7 meters (40 or 23 feet). There can be strong currents around the rock. Advanced divers can also explore several submerged pinnacles off Sail Rock, which are home to reef sharks.

Samran Pinnacles

The sister of Sail Rock, Samran Pinnacles is one of the most intriguing spots in the region. It features smaller pinnacles than Sail Rock but it is exposed to strong currents which makes dive centers hesitant to take just anyone there. As a result, it sees fewer visitors than other dive sites, which can only be a blessing for advanced divers that can take on the challenge. Marine life is abundant, ensuring close encounters with residents such as Malabar and Brown Marbled groupers.

Aow Leuk

Located off the southeast coast of the island, this bay is suitable for novice divers or those that prefer an easier dive. Although Aow Leuk means “deep bay”, it is only 12 meters deep (40 feet). Nonetheless, there is plenty to see in this shallow spot. Divers can easily encounter schooling barracudas, butterflyfish, sea turtles, and blue-spotted stingrays swimming over a variety of sea sponges and corals.

Green Rock

This rocky formation is located northwest of the island and features a multitude of interesting crevices and overhangs. The area is home to sea creatures like blue-spotted rays, white-eyed moray eels, and titan triggerfish. Some strong currents may occur around the rock.

Koh Yippon

One of the closest dive sites to Koh Samui is Koh Yippon, located within the Angthong Marine National Park. it offers beautiful overhangs and swim-throughs, as well as a diversity of hard and soft coral which have created the perfect habitat for marine creatures such as parrotfish, wrasses, and banded sea snakes.

Koh Wao

Also part of the Angthong Marine National Park, Koh Wao (“Sleeping Dragon”) is an island that features a shallow bay full of boulders. The calm water and the healthy number of hard and soft corals and anemones make it a great spot for scuba divers based in Koh Samui. Look around the sandy bottom to spot the stingrays.

Samran Pinnacles

Located right off Koh Samui, Samran Pinnacles is a draw for advanced divers. The site is filled with pinnacles that attract a large population of giant barracudas, jacks, and trevallies. You can also see a pretty display of soft corals and anemones, which cover the entirety of the pinnacles.
