In-depth guide · CampingSpirit
From the rock spires of the Chiricahua Mountains past mining towns and the Wild West to the saguaro forests of Tucson and the organ pipe cacti on the Mexican border.
The spirit of the route
From the plain of the Sulphur Springs Valley the Chiricahua Mountains rise like an island of stone. The Sky Islands are isolated mountain ranges in the desert where pines, oaks and desert plants meet within a few metres of altitude. Bonita Canyon is a forest of eroded rhyolite columns, at sunrise the rocks glow reddish, and at night the sky is so dark that the Milky Way seems to label the road. Further south Bisbee clings to the slopes of a former copper mine, Tombstone recalls Wyatt Earp and the shootout of 1881, and in the Dragoon Mountains Cochise hid. Near Tucson the saguaros stand with arms that point like signposts into the desert. At the end, on the border with Mexico, the organ pipe cacti grow in Organ Pipe Cactus National Monument, standing nowhere else in the USA in such numbers. The route thrives on contrasts: mountain and plain, ghost town and cactus forest, quiet and border history.
Stage-by-stage plan
1Stage 1: Willcox to Chiricahua National Monument (approx. 70 km)
- The drive
- From Willcox take AZ-186 south through the Sulphur Springs Valley, then into the Chiricahua Mountains to the access road via AZ-181. The road is two-lane and well built, with pasture and farmland at the edge. The last 8 miles in the park are winding; on Bonita Canyon Drive, according to the NPS, only vehicles and trailers under 29 ft (including carriers) are permitted, because a dip slows larger vehicles. Driving time is about 1.5 hours. Fuel stations in Willcox, none in the park.
- Highlights & must-sees
- Massai Point: a viewpoint at the end of Bonita Canyon Drive from which you see the rock spires (hoodoos) in the light of morning and evening.
- Echo Canyon Trail and Heart of Rocks: hikes through rhyolite columns; Heart of Rocks is the longer and more impressive option; avoid trails in summer after thunderstorms and in heat.
- Faraway Ranch: the historic ranch of the Erickson family in the park; tours and information from the NPS.
- CampingSpirit overnight tip
-
Official campsite or RV park: Bonita Canyon Campground (NPS) in the park: basic sites under oaks and juniper, water and toilets, no hook-ups; vehicles and trailers must be shorter than 29 ft (many sites are small, observe the NPS site map); reservations via Recreation.gov strongly recommended, and reservations are cancelled after 24 hours without arrival. As a reserve, private campgrounds in Willcox.
Free camping or nature tip (where legal): In the Coronado National Forest (Chiricahua Mountains) dispersed camping is allowed on forest roads, usually up to 14 days; access roads in part unpaved and unsuitable for motorhomes; check vehicle and weather. Not in the national monument itself.
- Insider tip for campers
- The monument is remote and dark: ideal for stars, but with little mobile reception. During the monsoon (June to September) flash floods can affect AZ-186 and AZ-181; check the weather. Never touch wildlife.
2Stage 2: Chiricahua National Monument to Tombstone (via Cochise Stronghold) (approx. 170 km)
- The drive
- From the Chiricahuas west via AZ-181 and US-191 to Sunsites, then on a forest road to Cochise Stronghold in the Dragoon Mountains, and finally via AZ-80 to Tombstone. Mostly two-lane roads, with a partly unpaved access road at the Stronghold. Driving time is around 3 hours; with stops, a day. Fuel stations in Willcox, Sunsites and Tombstone.
- Highlights & must-sees
- Cochise Stronghold: granite rocks in which the Apache leader Cochise defended himself in the 19th century; circular trails and photo stops at the rocks.

3Stage 3: Tombstone to Bisbee (approx. 45 km)
- The drive
- On AZ-80 across the hill country to Bisbee; the road leads through the Mule Mountains and through the Mule Pass Tunnel at the entrance to town (according to ADOT about 1,400 ft long, 42 ft wide and 23 ft high at the crown, uncritical for motorhomes). Bisbee lies in a narrow gorge, and the streets are steep and unsuitable for large motorhomes. Driving time is about 45 minutes. Fuel stations in Tombstone, Bisbee and Douglas.

Alternatively Coronado National Forest in the Huachuca Mountains.
Free camping or nature tip (where legal): BLM land and forest land in the surroundings allow dispersed camping, usually up to 14 days; because of the proximity to the border and use by border patrol, observe the advice.
- Insider tip for campers
- The centre of Bisbee is narrow and steep; park the motorhome on the edge of town and explore on foot. Thunderstorm rain in summer can close roads; check the weather.
4Stage 4: Bisbee to Tucson (approx. 160 km)
- The drive
- From Bisbee via AZ-92 through Sierra Vista and north via AZ-90 to Benson, then west on I-10 to Tucson. Well-built roads, pastureland and oak hills, a lot of traffic on I-10. Driving time is about 2.5 hours. Fuel stations in Sierra Vista, Benson and Tucson.

- Insider tip for campers
- For saguaro sunsets, head for the car park at Signal Hill or Gates Pass in good time; Gates Pass is narrow and unsuitable for large vehicles. Heat in summer: hikes early in the morning.

- Insider tip for campers
- According to the NPS, since 24 August 2026 several roads in Organ Pipe are closed because of construction work on border infrastructure: all cross connections south of South Puerto Blanco Drive, Grey’s Ranch Road and Camino de Dos Repúblicas; a 150-ft strip along the southern border is closed, while South Puerto Blanco Drive itself was open. Current information at nps.gov/orpi/planyourvisit/conditions.htm. Excursions to Mexico require a passport.
