The Santo António Caves (Grutas de Santo António) are one of the most impressive natural wonders of Portugal, located near the city of Fátima, in the picturesque Serras de Aire e Candeeiros Natural Park. These karst caves are the result of centuries of nature's work – for millions of years, water dissolved limestone rocks, creating an extensive system of underground chambers and corridors that capture the imagination.
