The Gruta das Banjas seemingly appears out of nowhere. A giant hole in the ground. The cave lies near the peak of Serra das Banjas, at roughly 325 m elevation, carved into schist bedrock with clear ties to abandoned mine workings. Features include tight passageways and vertical shafts—the result of manual extraction dating back to Roman and later periods, within the broader Dúrico-Beirão mining district. I’d recommend accessing from the western side, and climbing up and out of the main shaft, rather than the opposite way which demands a more challenging climb down into the chasm.
