The Western Ghats or Sahyadri (Tamil: சஹ்யாற்றி, Kannada: ಸಹ್ಯಾದ್ರಿ, Malayalam: സഹ്യാദ്രി, Marathi: सह्याद्री) are a mountain range that runs almost parallel to the western coast of the Indian peninsula, located entirely in India. It is a UNESCO World Heritage Site and is one of the eight "hottest hotspots" of biological diversity in the world. It is sometimes called the Great Escarpment of India.
