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.
