Caves and potholes in Colera

Colera, in the Alt Empordà, is one of the northernmost coastal municipalities in Catalonia, just a few kilometers from the French border, on a rugged stretch of the Cap de Creus coastline. The village retains remains of the former monastery of Sant Quirze de Colera. This steep, slate-and-granite coastline contains, in specific spots, a few coastal cavities.
