The Bujilices "Tumbao" Oak, located in Ucieda (Ruente) within the Saja-Besaya Natural Park, is one of Cantabria's most unique and magical trees. The tree fell under the weight of snow and wind at the end of the 19th century, but it didn't die. Four vertical branches sprouted from the fallen trunk, developing as if they were independent trees, creating a unique and spectacular shape.

There are several recreational areas with tables and barbecues, almost all with grills. There is also a huge children's playground and a bar that is open in summer. It has bathrooms, independent of the opening hours of the bar. Along the route of the Bayones River you will find the Ucieda pools where you can bathe.
