Nice little fishing village with a small beach, as a special feature even with a natural pool. From here you can always hike along the coast and sometimes you can also discuss with fishermen whether fish will bite.

February 1, 2026, Lago da Cascata

The Lake of the Waterfall (sometimes called the Lake with the Waterfall or the Lake of the Stone Steps) is one of the most photogenic and magical spots in Quinta da Regaleira. It forms part of the network of grottoes, tunnels, and symbolic gardens designed by Luigi Manini for Antonio Monteiro. This lake is usually reached through the underground tunnels that connect the Initiation Well with other parts of the estate; one of these tunnels leads directly to a hidden waterfall that flows into this lake.

The "Green Heart" of Cascais This park is the perfect peaceful retreat, blending nature, history, and leisure just steps away from the Marina. Key Highlights: Condes de Castro Guimarães Museum: A fairytale-like palace with a famous tower overlooking the water (a must-see). Roaming Animals: Famous for its free-roaming peacocks, ducks, and roosters, making it very popular with children. Chapel of São Sebastião: A small, historic chapel with beautiful tiles inside the park grounds. Activities: Great for picnics and family walks (lots of shade and playgrounds). Hosts a popular Organic Market on Saturday mornings. Venue for major events like the "Cascais Christmas Village."

The waterfall pool resembles a small natural basin, into which the water flows in gentle cascades – perfect for a short break while enjoying the interplay of water and rock. The water flow varies depending on the season, which also changes the atmosphere of the spot. Please stay on the paths and respect the sensitive shoreline so that this idyllic place remains intact.

Lago da Cascada is a mystical green lake. It can be admired and explored from every angle. Whether from the bridge, from above, or from the grotto... every view reveals a new side of the lake and its waterfall.
