This 48-mile route showcases sweeping views of three desert ranges and highlights the land's diverse history with two historical sites: Cocoraque Butte and the Titan II Missile Silo. Don’t let the mileage fool you; the rugged and sandy dirt roads make this a challenging ride…

Ironwood National Monument is known for its largest and richest stand of Ironwood trees. The Ironwood Overnighter highlights the region’s unique biodiversity while connecting two historical sites: the Titan II Missile Silo and Cocoraque Butte. Whether you want beautiful scenery, a secluded camping spot, or to learn more about the region’s history, this overnighter has much to offer everyone.

The Ironwood Overnighter is a bikepacking route designed to begin and end at the Titan II Missile Silo Interpretive Site, which is only a 40-minute drive from downtown Tucson, Arizona. This missile site was on alert during the Cold War period and manned around the clock for 24 years, from 1963 to 1987. From the interpretive site, the route goes on a smooth gravel road to a chunky power line descent that connects to a rugged climb.

Afterward, cow friends and large saguaros start to appear alongside the road. This is a sign to prepare your legs for the route’s hardest climb. After reaching the peak and taking in all the sights, a fun descent follows. Continuing on the rolling, rugged roads, watch for dispersed camping starting around the 15-mile marker. The 360-degree views of the desert ranges make it an ideal camping spot.

Rolling descents continue as you move away from the mountain ranges. Around the 22.5-mile marker, there is a turn-off to Cocoraque Butte (the O’odham name is Shontok). This historical site includes ancient Hohokam ruins, hundreds of well-preserved petroglyphs, and the historic Cocoraque Ranch. The age of the petroglyphs ranges from 1,150 to 2,000 years old. The hiking trail is about one mile out and back from the route.

Continuing along the route, the first sandy section begins for about a quarter mile. This is where larger tires and patience come in handy. After the sandy section, the route leaves Ironwood National Monument for a few miles through residential neighborhoods until you return to the monument trailhead. The Ironwood National Monument trailhead parking lot is a good spot for a water cache. Once you’re back in the monument, the second sandy section lasts about a half mile. Afterward, the route continues with meandering rugged dirt roads to fast, smooth gravel to a smooth pavement finish back to the Titan II Missile Silo parking lot.

Route Difficulty

Overall, the rating is 5 out of 10. Most of the difficulty is the need to carry water in a desert climate. There are a few cow troughs along the first half of the route, but they can be unreliable. I suggest carrying all your water and/or water caching along the route.

The climbing is relatively easy compared to the mileage, but don’t underestimate the terrain. In many sections, the roads are very chunky and rocky, so larger tires and front suspension would be ideal. Also, two sandy sections require a short hike-a-bike.

In terms of weather, the wind can get stronger as you move further away from the mountains. Limited shady spots and shoulder seasons can still have hot temperatures, so please be aware. Cell coverage with AT&T and T-Mobile were available on most of the route. The start and end at the Titan II Missile Silo parking lot makes it logistically easier.

Thanks to my partner Skyler Elzy for pre-riding the route twice and helping take photos. Thanks to Spencer J Harding for the original route recommendation and encouragement to visit the area.
