The first of 2 great cavernous scuba diving sites, 1st Cathedral is set up as a large room with many openings for light and sealife. The ceiling of the cathedral has many holes to bring in light and make this site a fantastic place to photograph. Inside is an alter-like boulder and a tube coral and sponge covered pinnacle in shades of orange and red. Outside of the cathedral is a 60 foot high arch and wall that makes this dive even more interesting.
From the main vaulted arch, 2nd Cathedral is sectioned into mulitple caverns. Among the many picturesque sealife here, Maui divers will find black coral, eels, prawns, and lobster hiding in the crevaces.
