In 1971 two hunters were chasing a fox who took refuge in a sink hole in the bushes. They entered in the cave and while they cross it they realize its beauty with galleries full of beautiful limestone formations. They discover the Grutas da Moeda (Coin Caves)
The Cave's viable extension is 350 meters length and 45 meters depth below the entrance point. Temperature is constant around 18 Cº all year round, which makes it easy to visit by all kinds of people.
