As you descend down the chain, large pinnacles of rock can be seen protruding up from the deep blue - the local Greeks call this site "kastro" or "the castle" because the pinnacles look like the battlements of a castle.
The dive is made around these pinnacles. The reef is full of marine life, from large and often free swimming moray eels, to schools of tuna hunting around the pinnacles. The pinnacles themselves are covered with reef life and are heaven for the macro-photographer. Large fishing nets which have snagged the pinnacles and been cut loose can be seen in places, now covered with featherduster fan worms and soft corals.
The dive is ended by swimming back to the anchor chain where a safety stop is made before surfacing.
