From the northwest, the mountains are the West Silver Bells, Silver Bell Mountains, Watermans, and then in the southwest the Roskruge Mountains. South of the Roskruge, Arizona Route 86 enters the valley from the Tohono O'odham Nation to the west. Robles Junction, Arizona, is also in the southwest, at the junction of the valley going southwest to Sasabe, the Altar Valley. Robles Junction is also at the northwest of the mountain range on Avra Valley's southern border, the Sierrita Mountains.
