You swim across a rocky reef of huge boulders in the channel formed between the columns and the cliff face. Grouper and bream are seen hiding amongst the rocks.
Eventually you pass the second column, and swimming around it brings you out to the wall on top of which the columns perch. It drops away below you out of sight and into the blue. If you are lucky, looking down you will see the silhouettes of large tuna, dentex or amberjacks hunting in the depths. Open Water dives will follow the wall at 18m and Advanced divers at 30m. Shoals of small fish are seen swimming back and forth along the wall and eventually the vertical wall flattens into a gently slope with reef-encrusted limestone boulders. Some very large grouper in excess of 2m live in holes between the rocks and can be seen darting away in the distance.
When the first diver reaches 100 bar, it's time to turn back. Ascending up the wall to 12m, you follow the wall back to the two columns and surface next to the boat.
