Best for intermediate divers, 7-20m, shore & boat entry, strong current.
Guillot Caves at Rigdon Bank offers a complex environment combining cave penetration, reef topography, and drift diving. Divers can explore depths ranging from 7 to 20 metres, with visibility typically between 10 and 30 metres. The site is suited for intermediate divers due to the overhead environment, sharp rock formations, and strong currents. Entry requires careful planning around the tidal cycle to manage current strength and avoid surf conditions. A boat is recommended for all entries to bypass the shore break. Divers must maintain precise buoyancy and situational awareness to navigate the caves and mitigate entanglement risks.
