    Rib Boat

This is another outstanding cavern which allows the diver to experience several other smaller caverns within one dive.  This is a huge cavern, so big where the rib boat takes divers inside this cave/cavern.

The ‘CATHERAL’ is a remarkable cavern as it allows you to travel through time. During Minoan times when the Santorini earthquake triggered a tsunami the Cathedral was immersed underwater.  This is evident as there are spectacular stalagmites and stalactites which reveal that at some point of time this cavern was found to be above water.  Its entrance is at 14 meters and in many areas there is a difference in temperature (+/-1 degrees) as you enter fresh water pools.  Another interesting feature is light beams coming down from the top of the cavern creating a very special effect.

This is one of our most interesting dives for certified divers and we recommend that you don’t miss this opportunity.

Blue Adventures Diving was the first to discover and survey this cavern and placed it on the dive map.  This dive site was one of the reasons we decided to open up our dive center in 1994 as we were mesmerized by its splendor.
