Why you should experience Calico Hills in Las Vegas, Nevada.
Calico Hills is a dramatic sandstone landscape where Red Rock Canyon's ancient geology, desert ecology, outdoor adventure, and scenic beauty create one of Southern Nevada's most recognizable natural destinations.
Set along Red Rock Canyon Scenic Drive between Sandstone Quarry and the Calico Hills Trailhead and just minutes from Red Rock Canyon Visitor Center, the area combines towering sandstone cliffs, winding hiking trails, internationally renowned climbing routes, and sweeping Mojave Desert vistas within one of Nevada's most celebrated geological settings. Brilliant bands of red, orange, pink, and cream-colored rock, weathered canyons, and sculpted outcrops establish an atmosphere defined by millions of years of natural history. Hikers, climbers, photographers, and geologists encounter remarkably varied terrain while following trails through formations shaped by ancient desert winds and persistent erosion. The result is a destination where geology, recreation, and conservation remain inseparably connected.
What you should know about Calico Hills.
Calico Hills is best known for exposing spectacular cliffs of Jurassic Aztec Sandstone deposited approximately 180 to 190 million years ago, when immense wind-blown dune fields covered much of the American Southwest before becoming lithified into one of the region's defining geological formations. The vivid red and orange coloration originates from iron oxide mineralization, while lighter cream-colored bands preserve portions of the sandstone that experienced comparatively little oxidation, producing the distinctive layered appearance visible throughout the landscape. Protected within the approximately 195,819-acre Red Rock Canyon National Conservation Area, the formations support internationally recognized rock climbing, hiking, photography, geological research, and habitat for desert bighorn sheep, Mojave yucca, creosote bush, and numerous native desert species. Continued stewardship by the Bureau of Land Management and long-term conservation efforts have established Calico Hills among Southern Nevada's most scientifically significant natural landscapes.
Geologist Edwin D. McKee fundamentally advanced scientific understanding of Aztec Sandstone by demonstrating that its immense cross-bedded formations originated from ancient wind-blown dunes rather than marine environments, making Calico Hills an internationally important reference for desert sedimentology. The Bureau of Land Management and the Southern Nevada Conservancy continue expanding geological interpretation through educational exhibits, guided programs, conservation initiatives, and scientific outreach that deepen public appreciation for the landscape's remarkable geological history. World-renowned climbing guidebooks produced by Falcon Guides and generations of professional climbers have documented hundreds of traditional and sport climbing routes across the exceptionally textured Aztec Sandstone, reinforcing Calico Hills' international reputation within the climbing community. Together Edwin D. McKee, the Bureau of Land Management, the Southern Nevada Conservancy, and decades of geological and climbing scholarship demonstrate why Calico Hills remains one of the American Southwest's defining sandstone landscapes.
How to fold Calico Hills into your trip.
Calico Hills is best experienced as a morning exploring the remarkable geology of Red Rock Canyon.
Begin at Red Rock Canyon Visitor Center, where interpretive exhibits, geological displays, and natural history exhibits establish the scientific context before continuing into Calico Hills, whose towering sandstone formations and winding trails become the centerpiece of the experience. Continue to High Point Overlook, where panoramic views across the Spring Mountains and Las Vegas Valley broaden the perspective after leaving the sandstone formations while revealing the immense landscape shaped by the same geological forces. Conclude at Spring Mountain Ranch State Park, where historic ranch buildings, mature cottonwood groves, and the dramatic Red Rock escarpment provide a memorable finale illustrating how generations of residents adapted to this rugged desert environment. The progression moves naturally from geological interpretation through immersive exploration before concluding with regional history, revealing the enduring relationship between Southern Nevada's landscape and human experience.
