Cathedral in Fortescue Bay is a boat-accessible site defined by dramatic rock formations, caverns, and swim-throughs. Reaching depths of 7 to 40 metres, this advanced site requires precise buoyancy control to navigate narrow tunnels and overhead environments. Visibility fluctuates between 9 and 40 metres, with water temperatures ranging from 13C to 18C. Due to the cold water, deep profile, and potential for entanglement in kelp or structures, appropriate thermal protection and advanced training are necessary. Divers should be prepared for mild to strong currents. Guided charters are recommended for initial visits to understand local current patterns and site navigation.
