From Tucson, take Interstate 10 west to Marana. Take Exit 236, turn left on Sandario Road for .1 mile, then turn right on Marana Road and go west about 5.8 miles to Silver Bell Road. Continue on Silver Bell Road to travel through the national monument. Visitors should have a detailed 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.
From I-10, take Exit 236 (Marana), head West towards the Circle K, taking Marana Road heading west. This road turns into Trico-Marana Road. Continue heading West until reaching Silverbell Road. Turn right on Silverbell Road. This road leads to the Monument and to the most popular area – the base of Ragged Top Mountain. If you turn south at the junction with Sasco Road, you will go around the Silverbell Mountiains and the Silverbell Road will turn into Avra Valley Road.
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. The Santa Cruz River crossing at Sasco Road is often closed and travelers should check road conditions with the Bureau of Land Management when planning to use this road.
