Buracas do Casmilo Private Hiking Tour from Coimbra

The Buracas do Casmilo (Casmilo caves) is an incredible and surprising monument sculpted by nature over thousands of years. They are the result of the collapse of the core part of a conduit – a speleological phenomenon called incassion – which exposed the extreme lateral parts, remnants of the cave that was previously hidden inside the mount.

These sinkholes are depressions where water is deposited; they serve, therefore, to support agriculture and pastoralism, representing true “oases in the desert”.

This fragile and crude artefact, whose structure allowed it to rotate in the most favorable direction, proves the ancestral art of using the wind to grind cereals.

From the top, you can see the mountains of Buçaco and Caramulo and the Serra da Estrela itself, on sunny days, shows its highest villages. The look still leads us to distinguish the entire coast, from Ovar to Peniche, to Figueira da Foz and the fields of Mondego.
