StandoutExceptional marine biodiversity

Naruhodo The Cave is a straightforward dive, perfect for newer divers. You'll drop to about 18 meters, exploring a small, swim-through cave system. Light filters in beautifully, illuminating the walls, and you'll often find small schools of fish sheltering inside. It’s a good spot to practice buoyancy in an overhead environment without any real challenge.
