Description

Vrelo Špilja is located in the Canyon of Matka, next to the springs of Koritiste, on the right bank of the Treska River. The cave has two huge halls, and two lakes. The small lake is 8 m long and 15 m deep. The large lake is 35 m long, 4 m wide, and 18 m deep. Highlight is a three metre high stalagmite, which is called Pine Cone because of its characteristic shape.

The cave was developed by the Peoni Speleological Society with financing from the Open Competition Fund of the EU Phare Cultural Development Program. The new developments were inaugurated in 2000.

The lower level of the cave is waterfilled. It is a 425 m long almost horizontal passage which fionally reaches a depth of 67 m below the water level. From here a deep shaft goes down at least to 330 m below the highest surface of the river. This made this cave the deepest waterfilled cave of the world for several years, however, since 2016 the deepest is Hranická propast in Czechia with -404 m, and this is only second. It is still the deepest spring in the Balkans.

The water cave was explored by the Italian cave diver Luigi Casati, who is part of an international team of explorers. Casati is using Aquatek Voyager rebreathers and a bail-out open circuit decompression line with different gas mixes. During the exploration he set a new world record for cold water rebreather cave diving. The exploration is still ongoing.
