Saga straddles the Dargye Tsangpo river above its junction with the Brahmaputra River. It is strategically located at the junction of three roads - the Lhartse road coming from the east, the Dzongka road from the south and the Purang and Drongpa roads from the west. Saga is also an important stop-off point for pilgrims and tourists on the way to visiting Mount Kailash being the last town on the southern route with supplies for travellers, having both a store and a restaurant and several guest houses and hotels.
