Don't use the entry shown in the aerial photograph, but drive all the way to the end of the parking area (by the pedestrian bridge over the pipes). There is a nice sandy entry area by the mangroves. It is a bit shallow but it is deep enough to swim around the patch of seagrass to the two boat mooring poles. Work your way towards the southwest (away from the main channel) until you are on the other side of the break water near the drop-off. We swam towards the main channel then back. One of the better reefs in Aruba Many varieties of coral, sponges , seafans. Nary an urchin to bother you on your way in or out.
