Question 1

How many technical dive centres are there in Gili Trawangan, Indonesia?

Question 2

Why learn technical diving in Gili Trawangan, Indonesia?

Accepted Answer

Indonesia sits in the heart of the Coral Triangle, the region with the greatest marine biodiversity on the planet, so the dives you train on are exceptional in their own right — Raja Ampat, Komodo, Bunaken and Lembeh in North Sulawesi, and the walls and currents of Alor. It also has cave diving: the karst of southeast Sulawesi holds hundreds of flooded caves, most still unexplored, with clear water, little flow and warm temperatures all year — conditions closer to Mexico than to most of Asia.

Accepted Answer
