Dive-site story
Cathedral forms a dramatic natural amphitheater positioned on the seaward edge of Aliwal Shoal. Large sandstone rock formations create an expansive crater entered through a sweeping overhead archway. Sand tiger sharks gather inside this sheltered bowl during their annual reproductive migration, often hovering motionless in the calm pocket of water protected from prevailing ocean currents.
Massive amphitheater-shaped geological bowl with a wide swim-through arch
