Pedra Furada and Pedra Furada Halt
Pedra Furada is a natural site on the Setúbal Peninsula, just south of Lisbon and near Sintra. Its distinctive sandstone tubes, formed during the Plio-Quaternary period, make it of interest to geology enthusiasts, hikers, and visitors exploring beyond Sintra’s main tourist routes. The formations are within the Sintra-Cascais Natural Park, an area of countryside, trails, and classified geomonuments.
Pedra Furada Halt (Paragem/Apeadeiro de Pedra Furada) is a modest rural transport stop in the Montelavar area of Sintra. It provides access to the surrounding countryside, hiking routes, and geological sites.
History and geological formation
Pedra Furada’s name means “Pierced Stone” and reflects the formations’ distinctive appearance as well as their place in local folklore. The Sintra and Setúbal areas also show evidence of prehistoric settlements and Roman occupation.
The sandstone tubes developed in a braided-river sedimentary environment, where alternating layers of sand and clay were deposited, cemented, and later sculpted by erosion (ScienceDirect). Studies suggest that fluid—water or gas—escaped through the sediment, possibly during rapid dewatering linked to seismic activity or sediment loading. Mineral precipitation along these pathways hardened the tubes and helped preserve them.
What to see
The sandstone tubes range from a few centimeters to 30 centimeters in diameter and can extend several meters vertically. They may branch and interconnect, with smooth surfaces and concentric internal layers. Their resistance to erosion compared with the surrounding rock creates the formations’ striking, hollowed appearance.
