The park contains the dinosaur footprints at Pedreira do Galinha, which are some of the longest sauropod trackways discovered worldwide.
The salt pans of Rio Maior are situated in an inland valley far from the coast, fed by a natural underground salt spring.
The park's limestone plateau is a critical aquifer for the region, feeding the Tagus and Lis river basins.
The cave systems are legally protected specifically to safeguard the high density and diversity of endemic bat populations.
The landscape is characterized by 'lapies,' a jagged limestone formation created by the dissolution of rock by rainwater.
Traditional 'cabana' architecture in the region uses limestone rubble-stone masonry without the use of mortar.
The Mira de Aire cave is recognized as one of the Seven Natural Wonders of Portugal due to its size and internal formations.
Parque Natural das Serras de Aire e Candeeiros is a 38,900-hectare protected karst landscape situated between the coastal plains and the interior of central Portugal. The park is defined by its extensive limestone plateau, which contains over 1,500 cataloged caves and significant groundwater systems. Notable geological features include the polje of Minde and the salt pans of Rio Maior, which have been harvested using traditional methods for over 800 years. The region is home to the largest dinosaur footprint site in the Iberian Peninsula, featuring tracks from the Middle Jurassic period. Flora consists primarily of Mediterranean scrub, holm oaks, and unique rupicolous vegetation adapted to rocky, calcium-rich soil. The area functions as a habitat for several species of bats, which utilize the park's deep cave systems for winter hibernation and summer nurseries. Traditional dry-stone wall construction is a prominent cultural element throughout the rural landscape. Visitor infrastructure includes marked hiking trails and access points to managed cave networks.
The elevated lookout points overlooking the polje of Minde or the patterns formed by the salt pans at Rio Maior.
Wear footwear with high-traction soles as the limestone karst terrain is sharp, uneven, and slippery when wet.
Carry a physical map or reliable GPS, as mobile reception is inconsistent across the plateau's remote ravines.
Visit the salt pans during the warmer months to witness traditional mineral harvesting in action.
Do not attempt to explore unmanaged, unmarked caves, as many contain dangerous vertical drops and unstable air quality.
Stay strictly on marked trails to avoid damaging fragile karst surface formations and disturbing cave-dwelling fauna.
