Bikini Reef lies just out to sea of the southern end of 2 Mile reef. It is dived in 3 main areas - the Northen Wall, Mellow Yellow on the southern end and Hopscotch, the deeper arm lying out to sea.

The cleaning station on the northern wall is a macro photographers dream, while huge schools of yellow snappers hang lazily in the nutrient rich mid waters on the southern end, giving it the name " Mellow Yellow"
