Lonesome Highway — Centennial Hills to Red Rock Canyon via the Sheep Range Crest
Vegas's forgotten wilderness — no casinos, no crowds.
Leave US-95 north of Las Vegas behind and push into the Sheep Range on the dirt roads threading through Corn Creek and the Desert National Wildlife Refuge — the largest wildlife refuge in the lower 48 and almost nobody drives it. The refuge roads wind through creosote flats, past bighorn sheep watering holes, and up into pinyon-juniper country on the Sheep Range crest before dropping south toward the sandstone escarpment of Red Rock Canyon National Conservation Area. It’s a loose, sandy desert run for most of its length, with the Sheep Range providing a dramatic skyline that Las Vegas sits in the shadow of but rarely visits. The Desert National Wildlife Refuge’s backcountry motor vehicle use map is required reading before you turn a wheel in here.
Most of this route sits between 2,500 and 7,000 feet — heat is the real enemy in summer, and desert sand the real enemy of unprepared rigs. Stock 4WD with high clearance and aired-down tires handles the terrain; deep sand sections on the refuge approach require proper sand recovery gear. Fall and spring are the right seasons — June through August is brutally hot and flash flood season hits hard in July and August. Las Vegas is your fuel and supply base, but the nearest reliable fuel on the north end is Corn Creek Road off US-95. No overnight camping inside the Desert National Wildlife Refuge without a backcountry permit. Red Rock Canyon has day-use fees. Cell service is gone the moment you leave the highway.

Frequently asked questions
Can a stock 4Runner or Wrangler handle this trail without modifications?
Yes — a stock 4WD high-clearance vehicle is the baseline requirement and will manage the route. Aired-down tires help on the sandy sections, and a longer wheelbase rig should watch for a few shelf road transitions near the Sheep Range crest.
Is this trail accessible in summer, or will the desert heat shut it down?
Summer is genuinely dangerous here — triple-digit temps, no shade, no water, and zero cell service make a breakdown life-threatening. Stick to October through April; the sweet spot is November to March when temps are manageable and the high country isn't buried in snow.
Do you need a permit to drive through Desert National Wildlife Refuge on this route?
Yes. The northern portion crosses Desert National Wildlife Refuge, managed by U.S. Fish & Wildlife Service, which requires a free refuge access permit — get it at the refuge entrance or ahead of time at fws.gov/refuge/desert. The southern BLM section has no permit requirement.
What's the hardest section of this trail and what should I actually be ready for?
The technical crux is the Sheep Range crest segment — loose decomposed granite, off-camber shelf road, and limited bailout options if conditions turn. It's not extreme, but a mistake here is a long way from help with zero cell service on the entire 55-mile route.
Where can I get gas and water before dropping into this route from Las Vegas?
Top off fuel in Las Vegas before leaving — there are no services for the entire 55 miles and the nearest gas on the Red Rock end is back toward the Vegas valley. Carry all your water; there are no reliable water sources on this route, and the desert will drain you faster than you expect.
