About Second Cathedral

This dive site is a cavern dive just like First Cathedral. One will notice that the main chamber has a split down the middle two huge and impressive archways. Second Cathedral is larger than that of First Cathedral and boasts a large amount of marine life including invertebrates and shrimp but be sure to bring a dive light. So that you can fully admire the roof where one can see black coral trees and tubastrea. When conditions permit, one can enter the site through the roof of the main chamber or go through a dark hole. There are very big and friendly trumpet fish at this site as well as big eels. Outside the large cavern one can see blue-stripe snappers and pyramid butterfly fish.
