For your day trip, we take you out on a fast transfer speed boat. It takes about 1.30 hours to reach the dive site, where you will rendezvous with our spacious dive boat, the MV Koon 9.

After a warm welcome aboard and a thorough briefing, you will get ready for their first dive. We dive in small groups to give you the best possible service and experience.

After the first dive, you will return to the MV Koon 9 for a buffet lunch and a more relaxed and extended surface interval. During lunch, there is plenty of time to sunbathe on our sun deck and relax. If you're feeling hot, then take a cooling break in the air-conditioned lounge before the second dive.

After the day’s excitement, the speed boat is ready and waiting to take you back to the Pier, returning at approximately 17:00 for transfers back to your hotel or resort.

“One of the best dive sites in Asia”

The world famous “Richelieu Rock” is waiting for you!!

Our Richelieu Rock diving daytrip will take you to this beautiful dive site in 1:30 with our fast speed boat.

Richelieu Rock is a massive underwater rock formation that holds an important diversity of marine life, from small seahorses to giant whale sharks. You will almost certainly find big schools of trevally and barracuda and other schooling fish such as snappers and fusiliers. The very top of the rock is just visible at low tide, but submerged at high tide. Below the surface, Richelieu Rock is approximately horseshoe shaped, consisting of several groups of rocks, pinnacles, overhangs, and small caves. It drops most steeply on the north and west sides, while the south side slopes more gently on the "inside" of the horseshoe. The maximum depth is about 35 meters, but it can be dived mostly at 20–28 meters. 

This is an amazing dive site, which is a true paradise for photographers and divers. You will make 2 dives at Richelieu Rock, and between dives, after the 1st dive, the boat will travel. We go to lunch Relax in Surin National Marine Park for about an hour and the boat will return for a second dive, which will give you plenty of time to explore this massive rock formation. You can dive as an Open Water there, but be aware of a bit more current. It’s nice if you have either the deep dive (30m) or Advanced certification so you can explore the full depth of the dive site.
