Sela Pass has located 78 km from Tawang and 340 km from Guwahati in Assam. It is unique and special, as it crosses a sub-range of the Himalayas and acts as a connecting point, between Tawang and the rest of India. Because of the extreme climate, the vegetation is scanty at Sela Pass. During winters, the Sela Lake freezes and is a sight to behold. It is believed to flow into the Nuranang waterfall that finally meets the Tawang River.
