From there, you can see the river, the surrounding vineyards and hills, and on clear days, the landscape becomes especially photogenic. It's close to other points of interest such as the Baloiço de Midões (a panoramic swing) and the Cais de Midões, a small marina.

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.

Gola do Salto is one of the most impressive waterfalls on the Paiva River — a narrow gorge where the river roars with force. It is located next to the Espiunca bridge, where a suspended viewpoint offers you a privileged view and a natural concert with the sound of the waters echoing beneath your feet. The walkway that follows this landscape makes the route comfortable and accessible, even on naturally rocky and uneven terrain.

The Gola do Salto is located next to the Ponte de Espiunca, on the Paiva River. As far as I know, kayaking is forbidden there.
