Petroglyph Canyon Trail: What to Know Before You Go
More than 300 rock art panels and roughly 1,700 individual carved images line the dark volcanic walls of this canyon south of Henderson — one of the largest concentrations of Native American petroglyphs in southern Nevada. The trail runs about 4.2 miles round trip through Sloan Canyon National Conservation Area, crossing a couple of minor dryfalls that require some hands-on scrambling before the canyon opens onto its main gallery of rock art. Desert bighorn sheep are spotted here often enough that it's worth scanning the surrounding slopes as you walk. Welcome to the Petroglyph Canyon Trail, one of the most culturally significant short hikes near Las Vegas.
Before You Go: The trail's permanent trailhead and access road, Nawghaw Poa Road, are closed for construction of a new visitor contact station through November 11, 2026. Hiking access is temporarily rerouted through Democracy Drive in Henderson. Check the BLM's Sloan Canyon NCA page for current access details before you go.

How to Reach the Trailhead
Sloan Canyon National Conservation Area sits south of Henderson, and its Petroglyph Canyon Trail is normally reached via Nawghaw Poa Road — Southern Paiute for "Mountain Sheep Trail." That road and its trailhead parking are currently closed while the BLM builds a new visitor contact station, larger parking lot, and interpretive loop, with a target completion of November 2026. In the meantime, access is rerouted through Democracy Drive. There's no fee to hike here, but confirm the current access route on BLM's website before you drive out, since the physical starting point differs from the trail's normal location for the duration of the closure.
What to Expect on the Trail
The trail follows the canyon floor through dark, weathered volcanic boulders, a real contrast to the red and white sandstone that dominates most other trails near Las Vegas. A couple of minor dry falls require some hands-on scrambling along the way, though nothing technical. As you near the main gallery, petroglyph panels start appearing on the canyon walls — pecked directly into the rock's dark desert varnish, exposing the lighter stone underneath. Keep watching the surrounding slopes as you go; desert bighorn sheep are seen here regularly, and this is one of the more reliable spots near Las Vegas for a sighting.
1,700 Carvings Spanning Centuries
More than 300 petroglyph panels and roughly 1,700 individual design elements are documented in Sloan Canyon, created across a span the BLM describes as running from the Archaic period into the historic era. The images are pecked into the canyon's dark volcanic rock varnish, a mineral coating that darkens boulder surfaces over thousands of years, so each carving exposes the lighter stone beneath. As with any petroglyph site, never touch or lean on the rock art — skin oils accelerate the same weathering process that took centuries to produce it.
Best Time to Visit and Conditions
October through May is the reliable window here — summer temperatures in this exposed canyon regularly exceed 110°F with no shade anywhere on the route. Morning starts are best both for cooler temperatures and better light on the petroglyph panels. Because access is currently rerouted for construction, allow extra time to find the temporary starting point on your first visit.
Practical Advice for New Visitors
- Check BLM's Sloan Canyon page for the current Democracy Drive reroute before heading out.
- Bring at least 2 to 3 liters of water per person.
- Wear sturdy shoes for the dry fall scrambling sections.
- Watch for rattlesnakes, including Mojave green rattlesnakes, especially in warmer months.
- Never touch or lean on the petroglyphs.
- Leave dogs at home — pets aren't allowed on this trail.
- Large or organized groups should call the BLM office ahead about permit requirements.
- Cell service is unreliable inside the canyon — download offline maps beforehand.
Few hikes this close to Las Vegas pack in as much cultural history as Petroglyph Canyon, and the chance of a bighorn sheep sighting adds a genuine wildlife payoff on top of it. The current construction closure is a real, if temporary, complication, so plan around it rather than around the trail's usual access point — and once you're there, treat the rock art with the same care that's kept it intact for centuries.
