THE SANDBANK IS SITUATED A MILE AWAY FROM THE HARBOUR OF  PALAU, IN FRONT OF ISLAND OF SANTO STEFANO. STARTS FROM A DEEP OF -16 METERS AND GOES DOWN GRADUALLY TO - 33 METERS. IT'S A BIG ROCK,  THAT TEEMS WITH FISHES AND RED-FANS WHICH ARE THE BIGGEST OF THE ENTIRE ARCHIPELAGO. ALL THIS LIFE IS THE RESULT  OF THE PRESENCE OF THE CURRENT ESPECIALLY WHEN WEST WINDS BLOW.
