Pou de la Calella
Geologically the Montgrí Massif is formed by carbonate Mesozoic sediments. This has enabled the appearance of karstification processes, most notably, the formation of shafts, sinkholes and caves.
The Pou de la Calella is the deepest, most extensive and most spectacular sinkhole in the Montgrí Massif, and is also the best known by speleologists in the area.
In l’Estartit, it is said that long ago someone fell into it and possibly ended up in the sea, as the body was never found. This story is hard to believe as there is no connection between the shaft and the cliff or the sea.
