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.

Be patient while queuing, but the entrance between the rocks is worth exploring. Be careful, the ground is wet and water is dripping from above.

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.

I think it's worth going in, even if you have to wait in line. You do have to be a little careful, because the lower you go, the darker it gets, and the stairs become more confusing. Once you get to the bottom, you'll have a breathtaking view up into the greenery.

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.
