Les Estunes Nature · Porqueres, Pla de l'Estany, Girona A natural site of rock formations beside the Estany de Banyoles, linked in popular tradition to the 'goges', the fairies of the lake. According to legend, they had their palaces here among the cracks in the rock, where they held feasts and spun thread all night long without anyone ever managing to see them. The formations are travertines of karstic origin, possibly the most important lake-formed deposit of this kind in Catalonia, formed when the waters of the Estany de Banyoles reached the site; the cracks that allow passage are the result of the fracturing and dissolution of the rock. On the travertine grows a wood of holm oaks and oaks, among them the Gros oak, near the Mas Corralot. It is reached from Banyoles by the road to Olot, past the Pujarnol crossroads.
