La grotte d'Harpea

A real geological curiosity in the Basque Country, the Harpea cave is a picturesque destination in the town of Estérençuby. It deserves to be the main part of an episode of your walks in Lower Navarre. Let's give it a long film with the entire valley of the Nive's sources as a backdrop, going up this pastoral corridor of a crazy aesthetic where the numerous springs and resurgences are as many extras giving the reply to the green curves. Because it is indeed here that the Nive finds its sources, in the plural, in each of the valleys, up to the feet of this incredible geological gift that is harpea (the cave, in Basque). When the weather is good, a return trip is possible.
