Dhonfanu is an oval shaped reef starting at a depth of 7 to 14 meters. One side of the Thila forms a beautiful swim-through beginning at 18 meters and ending around 25 meters. There is a canyon on the other side of the Thila between the main reef and a large block that stands slightly with astonishing corals and aquatic life. When the conditions are right, Grey reef sharks, Eagle rays, Barracudas and big schools of Jack fish can be seen.
The swim through was superb, and along our dive we found pipefish, groupers, bannerfish, featherstar, and lots of unicorn fish, with their big 'horn' sticking out their foreheads.
