Best for advanced divers, 38-41m, boat entry, strong current.
Heinz Cave is a challenging deep-water site located off Tablas Island, Philippines. The topography consists of a complex cave system, reef structure, and a drop-off, with depths ranging from 38 to 41 metres. Divers must navigate an overhead environment while contending with strong currents that can shift with little warning. Visibility typically fluctuates between 10 and 30 metres. Due to the significant depth, overhead hazards, and potential for drift, this site is strictly for advanced divers. Boat access is required, and the use of a surface marker buoy is essential. Night diving is an option for experienced divers who can manage the site's demanding conditions.
