    Calm yet vigorous, the Nabão River originates here, in the enigmatic Olhos d’Água de Ansião, where the water bursts from the rock and sees the light for the first time.

    In the heart of the Sicó Massif, the landscape here reveals itself shaped by water and limestone: gentle valleys, small floodplains, and an underground world of hidden galleries that reappear on the surface in seasonal springs.
