In the heart of the Serras de Aire e Candeeiros Natural Park, the Olhos d'Água do Alviela River Beach is located next to the source of the Alviela River and has cool, crystal clear waters. 

With beautiful surrounding countryside, this bathing area is part of a leisure complex that includes the Olhos d'Água Rural Campsite, as well as a playing field, children's playground, grassy areas, shaded areas, bar and restaurant. Nearby is the Alviela Science Centre - Carsoscópio, not to be missed if you want to learn more about the region.

For those looking for more physical activity, there is a mountain bike centre and several walking trails for exploring the vegetation that covers the mountains and the caves carved out by the river.
