Varkala is the only region in southern Kerala where cliffs are found adjacent to the Arabian Sea. These Cenozoic sedimentary formation cliffs are a unique geological feature on the otherwise flat Kerala coast, and are known among geologists as Varkala Formation. The cliffs have been declared a national geological monument by the Geological Survey of India for their protection, maintenance, promotion, and the enhancement of geotourism. There are numerous water spouts and spas on the sides of these cliffs. In 2015, the Ministry of Mines, the Government of India, and the Geological Survey of India (GSI) declared Varkala Cliffs a geo-heritage site.
