Frequently Asked Questions
When is the best time to see hummingbirds in Cave Creek Canyon?
Peak hummingbird season in Cave Creek Canyon is July through September, when monsoon moisture draws maximum insect activity and nectar production. Broad-billed, black-chinned, broad-tailed, rufous, and white-eared hummingbirds are commonly seen. Elegant trogon — a tropical bird that barely crosses the border — nests in the canyon May through August. The drive to Portal from Sierra Vista takes about 45 minutes on paved road.
What is the San Pedro Riparian National Conservation Area?
The San Pedro RNCA protects 40 miles of the last undammed river in the desert Southwest with year-round water. The riparian corridor is among the most biodiverse areas in North America — 350+ bird species, 80 mammal species, and 45 reptile species recorded. The river is a critical migration corridor. Access points along SR-90 between Sierra Vista and Benson have parking areas for walking the river trail.
Is Sierra Vista only for birdwatchers?
No, though birding is the main draw. Fort Huachuca has a military history museum (open to civilians with ID) covering the Buffalo Soldiers and counterintelligence history. Coronado National Memorial (15 miles south) marks the route of Francisco Vásquez de Coronado's 1540 expedition. The drive to Ramsey Canyon, Miller Canyon, and Carr Canyon offers beautiful mountain scenery even without binoculars.
