This gravel forest road FR 42 is the eastern part of the connection from the town of Portal at Cave Creek Canyon up and over the mountains before dropping down to Hwy 181 near the West entrance to Chiricahua National Monument. It connects to the paved end near Portal, labelled Cave Creek Road, while the section west of Onion Saddle is often labelled Pinery Canyon Road or South Pinery Canyon Road. The first four miles on Cave Creek Road from Portal are paved. Just before the Southwest Research Station at Herb Martyr Road (FR 42A) it turns to dirt and is a graded dirt road the rest of the way. It is rocky in places. In Cave Creek Canyon camping is only allowed in campgrounds. Once you are on National Forest land beyond the SW Research Station there are tons of dispersed camping sites all the way to the forest boundary.

Canelo Pass Road is a dirt road that takes from the ghost town of Canelo to the San Rafael Valley Road, an iconic gravel road through the open valley. This gravel road can be a bit rough at spots, but is generally well-maintained and well-graded. If completing on a road bike, make sure it can take wider tires; 35mm would be the minimum, 40mm+ would be more comfortable, and tubeless is a must. There are sharp rocks, the occasional cactus spike, and it's quite remote...

This is one of my favorite mountain passes in Southern Arizona-- in spring, there's often a little snow on top.

You'll find different mining remnants on Duquesne Road, but this old building/ruin is an eye-catcher.

From Shreve Saddle you have a breathtaking view to the Santa Catalina Mountains and into Pine Canyon. At this point the Molino Basin Trail and the Sycamore Reservoir Trail meet. The Arizona Trail winds its way very scenically along the rim of the mountain.

What does not kill you, makes you stronger. This is so true on the hike up from Romero Pass to Mount Lemmon along the Arizona Trail. This section of the trail defines the word "steep" totally new. Sometimes you will have to crawl on your feet and hands. But keep going, the landscape "up there" is gorgeous and worth the hard effort. By the way: you have a unique view from here and there is also a tiny spot for cowboy camping.

A mostly firm gravel road, steep in parts, leads up from the research station to Onion Saddle, with some considerable inclines - moderated by switchback in the upper third section.

For breathtaking vistas, consider Shreve Saddle, which offers expansive views of the Santa Catalina Mountains and Pine Canyon. Another excellent choice is Romero Pass, known for its unique views from higher elevations. Additionally, the drive along Mount Lemmon Highway (Catalina Highway) provides dramatic changes in scenery from desert to alpine forest, and Pinery Canyon offers magnificent views of the basin-and-range region.
Yes, you can explore Duquesne Road Mining Ruins, a historical site featuring various mining remnants, including an old building ruin. This pass also offers a unique perspective on the region's history.

Absolutely. Romero Pass is a challenging section of the Arizona Trail, known for its steep ascent that requires significant effort. For cyclists, the Trans-Mountain Road climb - Chiricahua NM East side offers a firm gravel road with considerable inclines, especially in its upper third section.
The Coronado National Forest is a 'sky island' region, meaning conditions vary significantly with elevation. Generally, spring and fall offer pleasant temperatures for exploring lower and mid-elevation passes. Higher elevation passes, like those accessed via Mount Lemmon Highway, provide a cool escape from the desert heat in summer and can even offer skiing in winter.
While specific 'family-friendly' categories aren't listed for all passes, many areas offer accessible sections or shorter trails suitable for families. The diverse ecosystems and scenic drives, such as parts of the Mount Lemmon Highway, can be enjoyed by all ages, with numerous picnic areas and viewpoints along the way.
The 'sky island' ecosystems of Coronado National Forest are incredibly biodiverse. You might spot a variety of birds, especially in areas like the Huachuca Mountains (Montezuma Pass) and Santa Rita Mountains (Box Canyon Road), which are renowned for birdwatching. Deer, javelina, and various smaller mammals are also common, with larger predators like mountain lions and black bears present but rarely seen.
The terrain varies greatly, from well-maintained gravel roads like Canelo Pass Road (Gravel) to rugged, steep trails such as the ascent to Romero Pass. Difficulty ranges from intermediate for many scenic drives and trails to challenging for specific climbs and longer hikes. Always check individual route details for specific elevation gains and surface conditions.
Stockton Pass in the PinaleΓ±o Mountains offers a quintessential southwestern experience. The route is characterized by large cattle ranches, rugged mountain ranges, and broad grasslands studded with desert plants, providing access to stunning landscapes and diverse ecosystems as you ascend.
Most mountain passes within the Coronado National Forest are accessible without specific permits for day use. However, some areas, especially those with developed recreation sites, may require a recreation pass (like the Coronado National Forest Pass or America the Beautiful Pass) for parking. It's always best to check the specific regulations for the area you plan to visit, as rules can vary.
The Coronado National Forest's mountain passes are unique due to their 'sky island' nature. They offer a remarkable transition of flora and fauna, ascending from Sonoran Desert to alpine forests within a relatively short distance. This creates diverse ecosystems and microclimates, providing a stark contrast to the more uniform desert landscapes found elsewhere in Arizona.
