Sail Rock. The No. 1 Dive site in the Gulf of Thailand came up trumps again today with 2 more Whalesharks there this morning. Don't think we have had a single guest this month who hasn't dived with a Whaleshark. But rather than boring everyone again with yet another photo of a Whaleshark here is a shot of a diver swimming through the vertical chimney at Sail Rock, one of the cooler things you will ever experience underwater... apart from diving with Whalesharks of course!
