The Gourgouthakas Precipice, the largest in Greece, is located in area of "Atzines" in the Lefka Ori Range near the Melidoni Peak. It was discovered in 1990 by the French Speleological Club "Catamaran" from Montbeliard, France. This group managed to reach a depth of -452 meters in 1996, of -985m in 1997 and finally, in August of 1998 they reached the bottom – a depth of -1208m. Here they found a lovely "siphon" (small lake with water). Reward for their efforts and persistence both in and outside of the chasm was the incomparable beauty of the falls, the gorge and the lake which has developed at the bottom of the cave.
