Map
During both winter and summer rains some of the roads become impassable. Always obey road closed signs on the monument. Cell coverage is very spotty on the IFNM and tow service is difficult to come by if you get stuck!
There are a number of ways to access the IFNM:
Taking Avra Valley Road - Silverbell loop gives visitors a great introduction to the beauty of the monument. Exit the I-10 Interstate at the Avra Valley Road exit and head West. Turn North on Pump Station Road, this road is a dirt road but for most of the year is easily traveled with any high clearance vehicle, at Silverbell Road turn back to the West. This route will lead you through the IFNM to a beautiful view of Ragged Top Mountain and around the back side of the Silver Bell Mountains. The loop rejoins Avra Valley Road and will take you right back out to Interstate 10.
Take Trico-Marana Road from I-10 to xx. Turn left and proceed a short distance to Silverbell and continue in either direction as described above.
Taking Sasco Road from the Red Rock exit off I-10, proceed west to the sign and turn left on to Silverbell Road. You can either follow Silverbell Road back to the freeway or take Pump Station to Avra Valley Road and return to the Interstate that way.
