The dive

Viroi is the spring lake by Gjirokastër. The cave starts at ~-30 m and visibility is at least 40 m according to the Belgian team; Polish divers give max 50 m.

Strong current at the entrance, cold and very deep; no hyperbaric chamber nearby.

This is how the planner decides who in your team may dive this cave. Rules your own trip adds (organizer, a mail, the AI) show with your trip.

How to get there

~3 km north-west of Gjirokastër, in the Lake Viroi natural monument. The road has a padlocked barrier: a custodian opened it after talks. Then you walk ~200 m and enter the water among the water plants.
