Serra d'Aire e Candeeiros Natural Park Adventures

Serra d'Aire e Candeeiros Natural Park, established in 1979, is a remarkable protected area covering the karstic mountain ranges of Serra d'Aire and Serra dos Candeeiros in Central Portugal. Spanning roughly 378 square kilometers across the districts of Leiria and Santarém, the park showcases a dramatic limestone plateau sculpted over millennia by natural erosion, featuring impressive caves, sinkholes, and underground rivers. The geology is the heart of the park’s allure, with extensive cavern systems such as the Mira de Aire Caves, one of the largest and most spectacular cave complexes open to the public in Portugal. Rich in biodiversity, the park hosts Mediterranean scrubland, endemic plant species, and diverse wildlife including birds of prey like the Bonelli's eagle and European roe deer. Historically, the area has been inhabited since prehistoric times, and archaeological sites within the park reveal early human presence and use of these caves. Outdoor recreation enthusiasts are drawn to its extensive trail network for hiking, mountain biking, and nature observation, as well as to spelunking opportunities in the park's caves. Notable landmarks include limestone cliffs, dramatic dolines, the Serra de Santo António viewpoint, and the town of Porto de Mós with its medieval castle. The park appeals to visitors seeking a blend of natural wonder, outdoors adventure, and cultural history in a uniquely rugged karst environment. The temperate Mediterranean climate supports year-round visits, though spring and fall are especially favored for mild weather. Visitor infrastructure includes several marked trails, guided tours for caves, and interpretation centers enhancing understanding of this geologically rich landscape.
