Cathedral Cave, ‘Eua

The Cathedral Cave, on 'Eua Island's northern tip, has long been regarded as one of the best dive sites in Tonga as well as in the South Pacific. It is a popular scuba diving spot that was discovered in 2001. It has a large cathedral and a 100-meter-long, 50-meter-wide, and 30-meter-deep underwater cave system. The cave has two entrances, one on the ocean side and the other on the land side, which are typically used by divers. The entrance is at 28 meters and is in a "current prone" area, so free diving is possible.

The Cathedral Cave has a large network of caves that experienced free divers can explore. With natural light filtering down to a sandy bottom 25-30 meters below, this amazing site is an underwater photographer's dream. The cave has a variety of entrances and provide a spectacular break from spearfishing or whale swimming. The cave system is home to crayfish.
