Chiricahua National Monument

Chiricahua National Monument, in the Chiricahua Mountains of southeastern Arizona — a “sky island” range rising to 9,700 feet from the surrounding Sonoran Desert grassland — preserves one of the most extraordinary rock landscapes in North America: thousands of towering rhyolite columns, balanced rocks, spires and pinnacles formed by the erosion of the Turkey Creek volcanic tuff into endlessly varied and surreal shapes, in a mountain range of profound ecological and historical significance.

The Chiricahua Mountains are one of the finest “sky island” birding destinations in the United States — the mountain forest (pine-oak woodland, Mexican pine forest) provides habitat for Mexican species at the northern limit of their range, making the Chiricahuas the premier destination in the US for rare Mexican birds. The monument is also the historical homeland of the Chiricahua Apache, and the hideout of Cochise. Chiricahua National Monument is a treasured natural and historical icon of Arizona.

Chiricahua National Monument offers hiking the spectacular trail network (17 miles of trail through the rhyolite formation landscape, including the Echo Canyon Trail, the Heart of Rocks Loop — the finest hiking experience in the monument, taking visitors through the densest concentration of balanced rocks and columns — and the Big Balanced Rock Trail; the trails require moderate fitness but are among the most visually extraordinary hiking experiences in the Southwest), birding (the Chiricahua Mountains are the premier sky-island birding destination in the United States, with Elegant Trogon, Sulphur-bellied Flycatcher, Painted Redstart, Arizona Woodpecker, Rivoli’s Hummingbird and Mexican Jay among the specialties — a target species list that draws birders from across the country), Bonita Canyon Drive (an 8-mile scenic drive through the monument, with pull-offs at the major formation viewpoints — accessible by passenger car), wildlife watching, photography, and stargazing (the monument’s remote location and dark sky are excellent). The rock formations, the Heart of Rocks hiking and the birding are the singular draws.

Late April through June is the finest season for birding (the Elegant Trogon is on territory and calling, the Sulphur-bellied Flycatcher has arrived, the hummingbirds are at the feeders at Rustler Park and the monument area, and the spring wildflowers are at their peak) and for the rock formations (the warm light and clear air are excellent for photography). The monsoon season (July and August) brings dramatic afternoon thunderstorms and clearing light; the rock formations in the clearing storm light are extraordinary. Fall (September through November) is excellent for hiking (cooler temperatures, the Mexican hummingbirds departing, the fall warblers moving through). Spring for birding, summer monsoon for storm photography, and fall for hiking are the highlights.

The Chiricahua Mountains are the historical homeland of the Chiricahua Apache, led by Cochise (whose stronghold in the Dragoon Mountains to the west and whose family’s territory in the Chiricahuas defined the last major free Apache presence in the American Southwest) and later by Geronimo (who was born in the Gila River headwaters and used the Chiricahuas as a base). The US Army established Fort Bowie (now a national historic site) in Apache Pass to control the spring — the critical water source on the Butterfield Stage route. The Chiricahua Apache were the last major Native American group to be subdued, surrendering in 1886 after a campaign that involved a third of the entire US Army. The rhyolite formation landscape of the monument was named “Wonderland of Rocks” by early homesteaders; the monument was established in 1924 by President Calvin Coolidge.

Chiricahua National Monument’s extraordinary rock landscape is carved from the Turkey Creek Volcanic Tuff — a massive deposit of volcanic ash and debris from the Turkey Creek caldera eruption approximately 27 million years ago (Oligocene), which deposited a layer of ash and tuff over 2,000 feet thick. The tuff cooled and welded into a hard rock with well-developed vertical joints. Subsequent erosion by water and frost has exploited these joints to carve the columns, pinnacles, balanced rocks and spires visible today. The erosion is ongoing — balanced rocks will eventually topple, columns will collapse, and new forms will emerge. The Turkey Creek caldera eruption, the welded tuff formation, the joint-controlled erosion and the sky-island uplift created Chiricahua’s geological character.

The Chiricahua Mountains are the finest sky-island birding destination in the United States — the mountain’s Mexican pine-oak woodland provides habitat for Elegant Trogon (the most sought-after bird in Arizona, nesting in the sycamore canyons), Sulphur-bellied Flycatcher, Painted Redstart, Arizona Woodpecker, Rivoli’s (formerly Magnificent) Hummingbird, Blue-throated Mountain-gem, Buff-breasted Flycatcher, and Mexican Jay. The Chiricahuas are the only reliable US location for the Thick-billed Parrot (occasional reintroduction attempts). Coatis (ring-tailed relatives of the raccoon), white-tailed deer, black bear, mountain lion, and the Chiricahua leopard frog (critically endangered) inhabit the mountains.

The Chiricahua Mountains are a “sky island” — an isolated mountain range rising from the Sonoran Desert grassland, with the mountain forest creating an ecological “island” of cool, moist habitat in a sea of hot desert. The sky-island ecology concentrates Mexican and Rocky Mountain species at the overlap of their ranges, creating the extraordinary biodiversity for which the Chiricahuas are famous. The Chiricahua leopard frog (critically endangered, native to a few mountain streams in the region) is a conservation priority. The Madrean pine-oak woodland of the Chiricahuas is a unique vegetation type shared with the Sierra Madre of Mexico; protecting the forest from fire, invasive species and climate change sustains the sky-island ecology.

Chiricahua National Monument holds a treasured place among the natural and historical icons of Arizona — one of the most extraordinary rock landscapes in the American Southwest, the homeland of the Chiricahua Apache, the finest sky-island birding destination in the United States, and one of the most undervisited and rewarding national monuments in the country. Its combination of surreal rhyolite formations, exceptional birding, Apache history and remote mountain character makes it exceptional. Chiricahua NM is a cherished natural and cultural icon of Arizona.

Chiricahua National Monument is in Cochise County, southeastern Arizona, accessible via AZ-186 east from Willcox (36 miles) or from Douglas via AZ-80 north and AZ-181 (about 60 miles). The monument entrance is at the end of AZ-181. Willcox (36 miles west) has services; Douglas (60 miles south, on the Mexican border) has full services. The Bonita Canyon Visitor Center is at the monument entrance. An NPS entrance fee applies (America the Beautiful Pass accepted). The Heart of Rocks area is accessible by trail from the visitor center (a 6-mile round trip with 1,000 feet of elevation gain). Check NPS for current trail conditions, visitor center hours and any fire or weather closures before visiting.

The National Park Service manages Chiricahua NM. The monument is in a fire-prone landscape — the Horseshoe 2 Fire (2011) burned through much of the Chiricahua Mountains and significantly affected the monument area; vegetation recovery is ongoing. Visitors help by following all fire rules (no campfires outside designated areas; no smoking on trails), respecting all wildlife (maintain distance from bears and other large mammals; the Chiricahua leopard frog is critically endangered and must not be disturbed in any stream), staying on designated trails (off-trail travel crushes the soil crust and damages the vegetation), and packing out all trash. Support the monument’s Arizona Sky Island conservation programs.

The monument’s trails involve significant elevation change (the Heart of Rocks loop gains/loses approximately 1,000 feet) and remote terrain (carry water and a trail map; no cell service in the monument). Afternoon thunderstorms are intense in the monsoon season (July-August; afternoon lightning is a serious hazard on exposed trails and ridges — descend from high terrain by noon during the monsoon). Black bears are present in the mountains; hang food at the campground. Mountain lions are present but rarely seen. Rattlesnakes (western diamondback, black-tailed rattlesnake) are present; watch your step on all trails. Respect the afternoon lightning, the bears and the rattlesnakes.

NPS entrance fee (America the Beautiful Pass accepted). Bonita Canyon Campground (available; check NPS for reservation vs. first-come rules). No fires outside designated areas. No collecting of rocks or fossils. Stay on designated trails. Pets on leash; not allowed on hiking trails. No drones. No touching the rhyolite formations. Pack out all trash. Check NPS for current fire restrictions, trail conditions and any closures before visiting.

Fort Bowie National Historic Site (25 miles northwest — the 3-mile round-trip trail to the ruins of the fort used in the Apache Wars is one of the finest historic hikes in Arizona), Willcox and the Sulphur Springs Valley (world-class sandhill crane and raptor watching in winter — up to 30,000 sandhill cranes in the Willcox playa in November-February), the Cochise Stronghold (in the Dragoon Mountains to the northwest — Cochise’s actual stronghold, a dramatic canyon hike), Douglas and the Agua Prieta border crossing, and the Portal-Cave Creek Canyon area on the east side of the Chiricahua Mountains (the finest birding location in Arizona, with a concentration of feeders and sky-island specialty birds in a private-land canyon) define the region. Portal-Cave Creek Canyon is 15 miles east of the monument and should not be missed by any birder visiting the Chiricahuas.

For the birding, drive to Cave Creek Canyon (Portal, AZ — 15 miles east of the monument on the east side of the mountains) and visit the Portal Peak Lodge and the Arizona Wilderness Coalition feeders for the Elegant Trogon (listen for its call — a frog-like repeated croak from the sycamore canyons — and wait at the known trogon territories along the creek). Hike the Heart of Rocks Loop (8 miles round trip from Massai Point) starting at sunrise when the light on the rhyolite columns is golden and no other visitors are on the trail. In late November-February, drive the Willcox playa (30 miles west) in the late afternoon to witness the sandhill crane roost flight — 20,000+ cranes coming in from all directions at sunset is one of the finest wildlife spectacles in Arizona.
