Caldeirão Waterfall (Pink Waterfall)

Cascata do Caldeirão, often known as Cascata Rosa, is one of the most distinctive natural sights in the Guarda area, within the Serra da Estrela Natural Park. Set near the Caldeirão Dam on the EM556, this waterfall stands out for the unusual pinkish tone of its rock walls, created by mineral oxidation and shaped over time by the force of the water.

With an impressive drop of around 50 metres, it offers a memorable contrast between rugged mountain scenery, flowing water and the soft salmon colour of the stone.

The waterfall is best reached via the Passadiços do Mondego, the wooden walkways that follow the Mondego valley between Videmonte and the Caldeirão Dam. From the dam area, access is relatively straightforward, with a short descent to viewpoints and an optional detour of about 2.5 kilometres from the main route to reach the top of the cascade.

The full walkway route is around 12 kilometres and includes many steps and some uneven sections, so comfortable footwear is recommended.

Spring and autumn are especially pleasant times to visit, when temperatures are milder and the surrounding vegetation is at its most colourful. The area is exposed, so bring water, sun protection and a windproof or waterproof layer.

Adventure activities such as canyoning or descent of the waterfall should only be attempted with experienced guides and suitable conditions.
