Petroglyph Canyon

Overview

Petroglyph Canyon is the short, sandy corridor followed by the Mouse’s Tank (Petroglyph Canyon) Trail. It packs an outsized payoff: hundreds of rock art panels carved into dark desert varnish on glowing red Aztec sandstone walls, all within an easy stroll.

What You’ll See

• Rock art everywhere—human figures, animals, and geometric patterns etched into patina-darkened rock. Many panels reveal themselves only when you slow down and scan carefully.
• Classic Valley of Fire scenery: narrow canyon walls, sculpted sandstone, and the namesake Mouse’s Tank—a natural basin that can hold water after rains—at the trail’s end.

Trail Snapshot

• Distance: about 0.7–0.8 miles round trip
• Difficulty: easy, with roughly 50 feet of total gain
• Surface: mostly loose sand with little to no shade
• Wayfinding: the petroglyphs begin almost immediately; few signs point to specific panels, so keep your eyes on both sides of the canyon.

History & Geology

People have visited and carved here for a very long time. Sources differ on exact ages: some panels may be around 1,500 years old, others older, and a few as recent as the 1800s. The art is pecked into the rock’s dark “desert varnish” that forms over centuries. The canyon’s vivid hues come from iron-rich Aztec sandstone. Mouse’s Tank is named for “Little Mouse,” a Southern Paiute man who hid in the area in the late 1800s.

Wildlife

This is an arid, exposed canyon—expect sparse sightings. Quick lizards and a few desert-adapted birds are the usual encounters.

Know Before You Go

• This is one of the park’s most popular stops—arrive early for a quieter experience.
• Heat is serious here; seasonal closures (often June–October) are reported due to dangerous temperatures.
• Amenities at the trailhead include a parking lot, vault toilets, and an interpretive kiosk. No water—bring your own.
• Cell service is spotty to variable.
• Leashed dogs are allowed. Do not touch or deface rock art; report vandalism.

Best Time to Visit

October–May is prime. Go at sunrise or early morning for cooler temps, fewer people, and flattering side light on petroglyph panels. Late afternoon also works; midday light is harsh and crowds peak.

Tips for Seeing More Panels

• Slow down and scan both sides of the canyon, especially patina-dark surfaces.
• On the return walk, look again—many first-timers spot additional panels only after their eyes “tune in.”
