Grotta del Fico

Grotta del Fico is a sea cave on the Costa di Baunei, formed in limestone by an ancient river system and marine activity.

Why it matters

The cave is associated with early scientific observations of Mediterranean monk seals. Explorers reported seals in its sea-connected waters in 1957, giving the cave an important place in the history of research on the species.

What to notice

The entrance lies above the sea and opens into galleries marked by stalactites, stalagmites and columns. A vertical shaft connects part of the cave to the sea, where water levels respond to the tides.

Context and history

The cave formed along the course of an ancient river over a long period of limestone erosion. Shepherds and fishers knew it before systematic exploration began in 1957. The writer Marcello Serra popularised the alternative name Grotta del Castello, while the older name Grotta del Fico remained in use.
