This cave is the most popular and most visited in Dénia and is located on the north face of Montgó, at about 350 metres above sea level. At the entrance of the cavity there is a Roman inscription, dated from the year 238 AD. Remains have also been found that show its use during the Iberian period and in the 4th and 5th centuries as a place of worship, and later in the Islamic period. At a certain point, it had a channelling by way of clay pipes that supplied water to the population settled on a part of the Montgó slope, dating from the 16th and 17th centuries.

How to get there: From the urban area of Dénia, take the Pou de La Muntanya path and then the Colònia path until the hermitage known as Ermita del Pare Pere. There, the PR-CV 152 path begins, going first back along Camí de La Colònia. Continue along the path for 1.4 kilometres until the crossroads, on the right, of Cova de L’Aigua.

Opening hours: Always open.
