Poncha Pass (9,010 ft/2,745 m) is a mountain pass in South-Central Colorado (USA). It lies between the San Luis Valley to the south and the valley of the Arkansas River to the north, and is one of the lowest mountain passes in the state. It is in the saddle between the Sangre de Cristo Range, lying to the southeast, and the Sawatch Range, lying to the west and northwest. The small town of Poncha Springs lies about 6 miles (9 km) north of the pass. The pass has a mild approach on the northern side and a moderate 5% approach from the south, though it remains open all year round and does not normally cause problems for vehicles in winter.
