Santa Rosa Blue Hole

No, it is not a mirage. This miraculously blue swimming hole is calm on the surface but hides a maze of mysteries. It is not only a place to cool off and relax but it is also the entrance to a system of underwater caves and tunnels which remained unexplored up until 2013. This doesn't include the ill-fated adventure of a couple of SCUBA divers in 1976 who died after becoming trapped in one of the caves. The 2013 dive did not uncover much information; the size of the tunnel system and where they branch off to still remain a mystery.
