Blue holes are four large holes in the reef plateau just a few feet below the surface. The holes are all connected to a single large cavern which is well lit by the holes above and from the large cavern entrance leading to the ocean. Make sure you catch the view looking back up holes as the rays of light shine down. At the back of the cavern the bottom sits around 28m/90ft inside, but this drops off very steeply as you move towards the main ocean opening making it very important to monitor your depth as you descend into and move around inside. There are several Flame File or Disco Clams, interesting Gobi's and their Shrimp partners and a cleaner shrimp grotto too. On leaving the Blue Holes, most dives finish by turning left along a beautiful reef wall which leads towards Blue Corner.
