From this point on the trail, you can enjoy spectacular views of Lake Sanabria. Located in the province of Zamora, at over 1,000 meters above sea level, it is the largest glacial lake on the Iberian Peninsula and the heart of the natural park that bears its name. Its clear, deep waters, surrounded by oak forests and peat bogs, unusual at this latitude, create a natural environment of great ecological richness. To make the most of your getaway, it is recommended to wear comfortable shoes and warm clothing, as the mountain weather can change rapidly.

Its waterfall is approximately 20 meters high, making it particularly impressive in spring and after rain.

Beautiful routes with spectacular viewpoints over the Lake on the Monks Route. During this time of year with the heat, it is better to do it at dawn until 1 pm maximum or after 7:00 pm.

Founded in the s. X by a group of Mozarabic monks, this monastery is the last preserved of the Zamora Cistercian buildings. Consolidated in the s. XII on a possible ancient Visigothic foundation, this late Romanesque monastery with a Renaissance façade embedded in the 16th century. XVI, still presides over Lake Sanabria. It is visitable, having a museum of sacred art and the well-preserved church.
