Round Papigo and particularly in the mountains Gamila and Astraka there are Caves like:
"Provatina", (depth: 408 m.) is one of the biggest vertical Caves in the world. The gulf was created by combined action of water and ice. In the depth of 180 m. there is a small loft with ice that never melts. There is also one room with a small lake and commemorative signs from Greek and foreign missions on the walls.
In particular, the gulf was located for the first time in 1965 by English speleologists (Cambridge University Caving Club). The first who tried to go down with rope-ladder was the English Jim Eyre (in 1966), who reached in a depth of 156 m, where he run out of rope-ladders. The following year, English soldiers used a mechanically-driven winch and basket and a wire rope for the descent. Their effort took place in two phases, first, up to the depth of 177 m. in the summer of 1967 and finally up to the bottom of the cavern (408 m.) in 1968.
The first speleologists who made an attempt with clearly speleological techniques were Frenches P. Sombardier and F. Poggia in 1976. From that time onwards many missions both foreign and Greek have gone down in the cavern. The first Greek that went down was Kostas Zoupis, a founding member of the Greek Speleological Expeditionary Group (G. SP.E.G), and member of ESE at the time. Many Greek and even more foreign missions visit each year the magnificent gulf. In 1998, the Speleological Hellenic Athletic Club tried to continue the exploration and attempted an ascent which did not attribute more depth but resulted in the discovery of some more small rooms.
The "Epos Chasm" is a scaled gulf with a depth of 451 m. Its creation is different from that of the "Provatina". The critical element is the existence of water since the cavern functions as a sink hole draining waters from the plateau. There are two different routes that one can follow, "Epos I", with a depth of 451 m. and "Epos II", with a depth of 340 m.
The "Hole of the Bride" (depth: 340 m). This cavern, like the ''Epos Chasm'' functions as a sink hole since it collects waters from the region. It is constituted by three big Caves (p150 m., p50 m, p120 m) and two small ones (p10 m. and p10 m.) which in the end are so narrow that you can hardly pass through.
The "Gkailotripa": with a depth of 200 m.
Recently, a new gulf, "the Hole of the carrion buzzard " (depth: 610 m.), was discovered by French speleologists and speleologists of the Speleological Hellenic Athletic Club. This exploration is continued up to now.
