In the region of Five Villas is the Natural Reserve of San Juan Xar that is the only autochthonous forest of weed of the Iberian Peninsula, although there are other tree species. Inside it is the shrine-hermitage-cave with a fountain of some pipes with fresh water that alleviates some pains: first you need to drink the water and then with a wet tissue you rub the painful area and then you leave it on the branches, closet o the fountain, before climbing to the hermitage you need to switch on a candle to the Saint. In the Southeast of this region the Natural Park of the Manor of Bertiz stands out with its botanical of 160 species in the cottage of Tenientetxea, where it is the Interpretation Centre of Nature. And among the Five Villas and Bertiz we can walk through the Green Way of Bidasoa.

Other natural area to highlight is the natural park of Peñas de Aya (in basque Aiako Harria) is in the western extrem of the province of Guipúzcoa, between the river Urumea and Bidasoa (the salmon comes back every year).
