Tech Diving Expedition: Sra Keow Cave

Technical divers explore Asia’s deepest documented underwater cave.

Ao Nang, Krabi, Thailand

Continuing the expedition James Foleher and James Thornton-Allan departed Phuket and drove south to Krabi province which is host to the deepest documented underwater cave in Asia called Sra Keow Cave located just outside a small beachfront town called Ao Nang.

Krabi is best known for towering limestone cliffs and jungle forests which cover the landscape located just south of Phuket on the west coast of Thailand.

Sra Keow Cave is a fresh water cave which starts at a depth of 12m and drops at a 45 degree angle vertically down to 240m. This is the deepest documented cave in Thailand as recorded by Big Blue Tech Instructor Trainer Ben Reymenants who reached the depth on open circuit trimix, his account of the story can be found here.

The purpose of this visit was to experience deep water caves and also use the entrance of the system to conduct a TDI Cavern Course within the light zone of around 20m inside the entrance.

The cave which is nestled in the jungle and home to elephants who use the fresh water pool to drink from is great contrast to the deep wreck diving experienced earlier in the expedition in the ocean.

Arriving at the pool edge the truck was parked, equipment setup and the divers jumped in at their leisure conducting 2 days of diving in and around the cave.

Mr. Foleher excelled at the skills and environment as he had overhead reeling experience already when he completed his TDI Advanced Wreck on Koh Tao before departing on the expedition. The TDI Advanced Wreck and his recent TDI Cavern Course covers the majority of overhead environments found in technical diving.

These courses open up the world of cave diving which he is now eligible to get involved in.
