The Los Estoraques Unique Natural Area (Spanish: Área Natural Única Los Estoraques) is one of the smaller national parks, covering only 6 km (2.3 sq mi), located in the Cordillera Oriental of Colombia in the Norte de Santander Department. The landscape is shaped by large brownstone pedestals and columns formed by thousands of years of erosion.[1] The area is part of the Catatumbo River basin and elevation range from 1,450 to 1,900 meters above mean sea level. It was declared a Área Natural Única (Unique Natural Area) in 1998.[2]
