Rodeo, New MexicoThe Quiet Side of the Chiricahuas.

Portal gets the postcards. Rodeo is where the road goes quiet — a hundred-odd people on the New Mexico side of the line, with the Sky Islands out the window and some of the darkest skies left in the country overhead.

Biodiversity

A Sky Island Sanctuary

Rodeo sits in the San Simon Valley where Chihuahuan desert grassland runs up against the largest Sky Island range in the region. Climb from the valley floor to the Chiricahua crest and you pass through desert scrub, oak woodland, pine and fir in the space of an afternoon — with birds and reptiles that reach no further north than here.

Roger Tory Peterson counted Cave Creek Canyon, ten minutes west of town, among the great birding places in North America. Thirty-five kinds of rattlesnake occur in the surrounding country. Most visitors come for one and stay curious about the other.

Nocturnal Wonders

Where the Milky Way casts a shadow.

There are no streetlights in Rodeo and no city within a hundred miles of the horizon. Astronomers moved here on purpose: the valley sits in one of the darkest, driest, steadiest patches of sky in North America.

Bring your own darkness

No permit, no gate, no fee. Pull off a side road, let your eyes adapt for twenty minutes, and use a red light. The zodiacal band is visible on a good night.

03

Best nights

New moon, October through May, when the monsoon humidity is gone. Winter nights are cold at this elevation — dress as though you were standing still for hours, because you will be.

Practical notes

Where is Rodeo, New Mexico?

Rodeo sits in the far southwest corner of New Mexico, in Hidalgo County on US Highway 80, about 4 miles east of the Arizona state line and 30 miles north of the Mexican border. Portal, Arizona is 10 minutes west; Douglas is about an hour south, Lordsburg an hour north, and Tucson roughly three hours west. ZIP code 88056, elevation 4,128 feet, Mountain Time.

Getting here

Tucson International is the usual gateway, roughly two and a half to three hours west via I-10 and Highway 80; El Paso is a comparable drive east. Rodeo's airstrip (NM70) is private-use and unattended.

Fuel & supplies

Services here are minimal and hours are informal. Fill the tank in Lordsburg, Willcox or Douglas before you turn off, carry water, and treat half a tank as empty once you start up the canyon roads.

Phones & internet

Cell coverage is patchy in the valley and mostly absent in the canyons. Make lodging arrangements and download maps before you arrive — it may be a while before your phone works again, which is part of the point.

Roads & weather

Portal Road is partly unpaved and washes can run during monsoon storms. Never drive into moving water. The mountain road over the Chiricahuas is unsuitable for large RVs and trailers.

A little history

Rodeo began in 1902 as a siding on the El Paso & Southwestern Railroad, moving Bisbee copper ore east. This was Chiricahua Apache homeland long before that; Geronimo and his band held out in these mountains until 1886.

Go easy on the place

Most land off the highway is private or ranch land. Keep gates as you found them, stay on established roads, shield your lights at night, and keep back from nesting birds.
