The main site of interest here is Napantaw Fish Sanctuary, which is also known as Rio's or Toshi's Wall. It is certainly worth a visit for the diversity of marine life on offer.
If you have the time on the dive, there is a cave at 40m that is worth investigating. If not, the sights at shallower depths are impressive. There is a good chance to see turtles, barracuda, groupers and batfish among others. As currents are strong here, coral formations are impressive with gorgonians and black and soft coral everywhere.
