amazing place for a night dive, only 5mins by boat from Semporna. Look for the red marker buoy that is bent. Reef starts very shallow at 3m, on my first dive there, the first fish i saw was a Shaggy Frogfish!! Reef goes down to a sandy bottom at 13m, where you can find anything and everything macro!! this is such an amazing night dive.
