Lost deep down in time, the myths wanted the Agios Nikolaos Lagoon Canyon to be an Abyss, a bottomless lake knitted around countless stories. In 1945 it is said that the German fleeing in it all their light and heavy weapons so as not to fall into the hands of the Cretans!!!

Hiridoni is a unique cave - cenote exploration challenge along with Agia Eleousa and Ag. Theodore cenotes.
In 2001 such a mission was an extreme situation that seemed very difficult.
Previous exploration there had been carried out by Vassilis Giannopoulos' team with Jean-Jacques Bolanz, Louigi Casati and Patrick Deriaz.

Having explored the cenotes / lakes /caves of Melisani, Karavomilos, Angalaki, Zervati and the incredible Hiridoni we decided to explore the scary cenote of Agia Eleousa.
Dark, inaccessible, scary, with its inferior inner world a challenge. We got all information needed from pioneer Mr. Vassilis Giannopoulos.
24 February – 3 March 2009
One of the well-known cenotes – cave / underwater lake of the area in Sami is the cave of Aggalaki.
The diving team consisted of George Petrou, Nassos Zervopoulos, Kipraios Tasos and Gravanis Elias. We walked the magnificent inland cave, full of bats, stalactites, stalagmites and turquoise ponds. We dived into the lake with the stalactites of “ages” hanging above us. Spectacular, green, luminous atoll with easy accessibility.

After completing the successful expedition to Ag. Nikolaos cenote in Crete, our team began to "discuss" what her next mission would be.So I ordered all parts of the group to submit proposals. The proposal fell like a dynamite from George Vandoros and was immediately approved.
24 February – 3 March 2009
Undoubtedly the most famous lake cave of Kefalonia is Melissani with myths and legends lost for centuries.
A very spectacular terrestrial and underwater environment, the ultimate symbol of the area.
The HUEs came for another exploration with a small team this time consisting of Giorgos Petrou, Nassos Zervopoulos, Cypraios Tassos and Gravanis Elias.

Zervati with its two cave - lake system friendly cenote with easy access.Ideal for training and adapting to similar terrestrial and underwater environment for cave diving.
A small turquoise vegetation paradise between the houses of the village.
The team consisted of:
George PetrouNassos ZervopoulosCypraios TassosGravanis Elias. Delightful and relaxing diving where a small amount of gas is required without engaging in decompression times.
22- 24 June 2018
With Pantelis Fitilis we decided on a two-day excursion. We chose the Karavomilos Cave and the Submarine Perseus in Kefalonia.
Karavomilos: one of the easiest cave diving due to its easy access and the "cozy" interior of the cave which develops beneath the church and village houses.

Some time ago a small team of three passioned technical divers and Instructors, went as pioneers and scouted, researched and dived into the lake, gathering information on the wider area.

Shipwrecks have always fascinated scuba divers. Malta is an island of shipwreck besides the Knights Island. Tankers, Submarines, Tugboats, Airplanes and everything else anyone can imagine is there.
