Dive, Snorkel or Freedive in Koh Rok with Phoenix Divers Koh Lanta

and have the time of your life! Koh Rok is a Thailand island south of Koh Lanta that is a part of the Mu Koh Lanta Marine National Park. Diving, freediving and snorkeling in Koh Rok is famous thanks to the amazing corals and white sandy beaches. Unlike any other islands surrounding Koh Lanta, you can take a walk inside the island and find tourist facilities such as toilets or restaurant. Scuba diving is not difficult as there isn’t much underwater current and the visibility is usually great. There are many macro species living in Koh Rok, such as anemone fish and nudibranchs that are residents here. In addition, a turtle can be spotted very often while diving, making this place a tropical paradise.

Koh Rok Diving spots are divided in two amazing islands: Koh Rok Noi and Koh Rok Yai

as you might already know Noi means small and Yai means big. Both islands have many places suitable for diving, freediving and snorkeling. Moreover, both islands are surrounded by white sand beaches where you can relax. Some of the beaches are very remote and can be only accessed by a small boat like ours! Therefore, there are many nice corners we have to choose between for our perfect diving or snorkeling day. All this in absolute relaxation and without other diving boats around.

Koh Rok is a perfect trip for mixed families of divers and non-divers

Diving Koh Rok trip is perfect if you wish to bring your non-diving family. Your loved ones can enjoy the best snorkeling sites available from Koh Lanta Island while you are underwater. Or, if you family isn’t a fan of water, they can relax on the sandy beach or walk around the island. Give them an unforgettable day of relaxation while you pursue your passion!

Unforgettable experience for beginner Freedivers

If you are just beginning your adventure with freediving, Koh Rok is the perfect place. The abundant sea life makes the diving more enjoyable. Watching the amazing creatures makes you forget you are holding your breath! In addition, the visibility usually allows you to see the bottom which for some beginners take the fear away. Sign up for the AIDA* or PADI Freediver courses and see for yourself!

Typical Diving Day Trip

With our fast and comfy speedboat, it takes less than one hour to arrive to this amazing location. A typical day in Koh Rok includes 2 or 3 dives, depending on the group we have on the boat. We let our scuba divers and snorkelers decide with us! In between, we serve you fresh fruits, cold drinks and snacks. For lunch, we stop on one of the white sandy beaches and enjoy our meal on land. It’s truly a day to never forget.
