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 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.
