Saturday 05th December 2015


Our guests arrived around 17:00 so we got our gear set up with excitement, had our welcome briefing followed by the fire crackers festival, dinner and bed, all looking forward for a great week of diving.



Sunday 06th December 2015


We arrived in the Similan National Park around 4:00 so just enough time for helm crew to take some rest and start our first day of diving. Check dive was done at Anita’s reef where visibility was above 30 metres and there was a lot of marine life. We saw some tiny nudis, blue spotted sting rays, scorpion fish and thousands of glass fish. The day carried on with turtles, dog tooth tunas, giant trevallies topped by the amazing granite boulders only Similans has to offer. What a great start.



Monday 07th December 2015


We made our way to island number 8 and 9 and it only got better. We had about 35 metres visibility, really showing the massive granite boulders the Similan National Park has to offer. Plenty of marine life, from very small to larger ones such as nudis, blue spotted sting rays to the dozens, mantis shrimp, Durban dancing shrimps, moray eels, turtles, giant trevallies and a massive great barracuda, measuring up to two metres in length.



Tuesday 08th December 2015


Time to head north so we started our day with two dives in Koh Bon. We still have great visibility and an abundance of fish. Koh Bon has a very different topography when comparing to Similans islands one to nine, having great limestone structures, instead of the granite boulders. While diving in such topography, we saw many pipefish, mantis shrimps, banded cleaner shrimp, Maldivian sponge snails, thanks to the cracks and crevices it has to offer. We also saw a large school of jacks, emperors and rainbow runners hunting together and some believed there were more than one thousand. We did our last dives of the day at Tachai and we saw large schools of barracudas, giant trevallies and a lot of macro life too. What an incredible day, it just gets better and better.



Wednesday 09th December 2015


Here we are again, at Richelieu rock, our favorite dive site. It does not matter how often you dive at this site, we will always have a blast. We did four dives at Richelieu rock and we came across a lot of marine life. The usual mating cuttlefish made their show, posing to our divers and everyone loved it. We also saw a large school of barracudas, many emperors and giant trevallies hunting, topped by mantis shrimps, nudis, scorpion fish and a very well camouflaged frog fish. What an amazing day.



Thursday 10th December 2015.


We are back to Koh Bon and Koh Tachai for some more great dives. Currents have picked up, bringing a lot of actions with it. We saw turtles, mantis shrimp, nudis, emperors, jacks, trevallies, many moray eels, octopus and a lot of schooling snappers, fusiliers and blue fin jacks. In Koh Bon, with some swell, we managed to watch the beautiful underwater water fall where a flow of water runs through the island and drop it underwater.



Friday 11th December 2015


What a great last day. Visibility was great and we explored the swim throughs of Elephant head rock, topped by some massive sea fans and soft corals. There were a lot of fish such as sting rays, blennies, dog tooth tunas, banded sea krait and many glass fish. Time to head back to Chalong pier, a eight hour sailing time, then BBQ and spend some quality time with such a great group.



Saturday 12th December 2015


Time to go home everybody and thank you for such a wonderful week. Hope to see you all soon again.
