The Maddoo Giri was absolutely fantastic. Its a strangle old reef being 25m-30m at its deepest, and 3m on top. There's an absolutely breathtaking swim through / hole on the northern side of the reef. We dropped on the western side into 28m, and swam around to the north to investigate some of the reef. About half way along the length, we turned around and headed back to the openning for the swim through.
The openning of the swim through is in 25-30m, and then ascends up to the top of the reef at 3m. Its like a big hole, dug at a 45 degree angle from top to bottom. Inside, its beautiful. Lots of wildlife, and a great view upwards. A great dive to take your time over!
