Although the tour is quite short, it thrilled us. On warm days (it was 32 degrees for us) the tour was sweaty. Currently, the authorities have closed the path, a short section of 15 meters has slipped. However, the spot can be easily and safely bypassed.

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.

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 😀!
