Caves and potholes in Ullà

Ullà, in the Baix Empordà, sits on the alluvial plain of the river Ter, not far from Torroella de Montgrí and the Montgrí massif. The municipal area, mostly flat and agricultural, typical of the Empordà plain, contrasts with the nearby limestone relief, and the catalogue of cavities reflects this situation of low-lying land by the river.
