Koh Racha is located within close proximity to Phuket, but it offers a completely different atmosphere. While Phuket is known for its vibrant party atmosphere and nightlife, Koh Rocha is better suited for those who seek a tropical escape. The island of Koh Racha offers gorgeous white, sandy beaches and plenty of great diving options.


When looking for the best dive destinations near the Andaman Sea, Koh Racha is one of those options. Its location south of Phuket makes it ideal for all types of diving and for all levels of divers.

One of the most notable reasons why avid divers come to Koh Racha is due to the quality of marine life available. The coral reef forest is also rich and thriving. It is an astonishing view to marvel at for diving enthusiasts who come to Koh Racha.

During the diving season, and even during off-season, divers who come to Koh Racha are impressed with what they find. The actual dive center is located on the island of Koh Racha. You can explore rock formations, boulders, coral reefs, and shipwrecks during your dive.

Bungalow Bay

The Bungalow Bay is one of the first spots that divers go to in Koh Racha. The great thing about the Bungalow Bay is that it is suitable for those who are still learning how to dive. The reason behind its popularity is due to the great diving conditions, especially during the high season. The site is protected from the easterly weather so you can ensure maximum visibility and stable currents.

This dive site is divided into two main areas: North and South Reef. The North Reef consists of mainly boulders and small rock formations. When it comes to marine life, you will stumble upon cleaner wrasse, barracuda, trigger fish, butterfly fish, and more. As for the South Reef, it is best suited for those divers seeking to obtain their PADI certificate. It is also a popular destination for underwater photography.

Siam Bay

This bay is located at the northernmost point of the island of Racha Yai in Koh Racha. It is famous for the rocky edges and sand at the center of the bay that is filled with hard coral patches. As an added attraction, you can also find man-made structures at the center of the bay of two big elephants, along with a giant temple gate.

HomeRun Reef

Because this dive site is located north of the eastern portion of Racha Yai, this site is often the last destination for a diving day trip. In this dive site, you will encounter a lot of marine life including branch, staghorn, and pore coral. This dive site is recommended for divers of all skill level. But you have to be careful when diving this area because the current coming from the north is strong, so extra caution is needed.

Staghorn Reef

This reef dive site is located right in the middle of Bay 2 and Bay 3 in Koh Racha. The dive site is named as such because the underwater sightings in the area consist mainly of Staghorn Coral. But it is also possible to find other types of coral such as pore coral and branch coral. This site offers a maximum dive depth of 20 meters, though some portions can go as deep as 40 meters. Sadly, this site suffered from bleaching in 2010 due to climactic conditions.

Racha Yai Wrecks

There are a total of four shipwrecks that are located in the areas within Bays 1 and 2 of Koh Racha. One of them is a sailboat wreck, which is a great site to go to when you want to marvel at the rich marine life that has thrived here. When exploring the shipwreck, you will find glass fish and snappers. It is also possible to spot giant moray eels and barracudas.

The Harruby Liveboard is another great wreck site to dive in Koh Racha. The dive site is around 20 meters below the surface with the top portion accessible at 14 meters. It is an easy to access site for all types of divers. This wreck site is great for penetration, although you must have completed the PADI specialty course before you can do that.

Just like most dive sites in Thailand, the diving conditions in Koh Racha are suitable throughout the year.

One thing that you should be wary about when diving from May to October is that the undertow can be strong. This is potentially dangerous.

For maximum water visibility and stable currents, the best time for diving is anywhere from November to April.

Koh Rocha consists of twin islands that are located off the southeastern coast of Phuket. These two islands are Koh Racha Yai and Koh Racha Noi. These two islands are popular diving sites in Thailand, but also known for the crystal blue waters and gorgeous idyllic beaches.

Because these islands are not as crowded as Phuket is, they are considered an exclusive paradise for diving enthusiasts. The islands are only accessible by boat, either longtail boats, speedboats, or dive boats.

These two islands have their respective dive site options available. But the diving conditions for each of these islands can be significantly different; hence, it is important to know ahead because some dives are better suited for expert divers.
