March 30, 2025, Nascente do Rio Lis

The Lis River, whose source is in the town of Fontes, Cortes, is one of the few rivers in the country whose current flows from south to north and, in the final kilometres, from east to west. In winter and early spring, it is possible to see water emerging from the ground in surprising quantities. In the summer months, the source is usually dry.

The Sheep's Sink is an imposing natural cavity, named after the sink carved under a stalactite that, in the rainy months, pours out abundant water. In the past, this natural refuge served as a drinking trough for cattle.

While the spring itself is dry in summer it must be spectacular when the rains are back in November. But the Rio Lis is also fed by water coming from inside the mountain and ground-water from the area, so water starts flowing a few hundred meters further down the riverbed, nice and fresh. There is a lovely path following it, and those who did some walking on a lovely summers day will really enjoy a little dip, maybe some swimming, but at least a bit of wading through it. There is easy access in several places, have fun 😀!

headwater of the Lis river, a river that cross the city of Leiria and flows into Praia da Vieira. An amazing place to visit during the winter and after some heavy raisn, where you can see the water coming from the earth.
