Song Hong Exploration Expedition

Song Hong Sinkhole

In the next few weeks Davy Jones’ Tech are planning a trip to Song Hong sinkhole in the south of Thailand. Led by head Technical Instructor David, we are planning a Trimix dive to 100m in the sink hole. 3 other divers who are Trimix and Full Cave certified will accompany us. Song Hong lake is the gateway to a huge underground river. It is believed to flow all the way to the sea which is over 60km away. Where it flows to and from is unknown due to its depth and sheer size.

The deepest dive made in the cave was 140m and over a kilometer in, and this barley scratches the surface. The purpose of this trip is to try to explore more parts of the cave and have some fun at the same time! The roof of the cave starts at 40m and when you are on the main line you cannot see the bottom or any other walls. This is despite the water being crystal clear below 30m. It is a great dive, especially if you have an interest in cave diving and the possibilities of exploration that it offers.
