Ruta de los Dinosaurios Coahuila Desert Circuit
Desert dinosaur hunting through Cretaceous badlands
This 180-kilometer backcountry loop cuts through the Sabinas Basin near Saltillo, where 70-million-year-old Cretaceous fossils weather out of exposed badlands. The route follows ranch roads and fossil hunter tracks through the desert where Coahuilaceratops and other Mexican dinosaur species were discovered, crossing dry arroyos and navigating around massive gypsum deposits left from ancient seas. Key waypoints include the Cerro del Pueblo Formation exposures and the technical descent into Cañón de la Hacienda.
Moderate to difficult rating due to loose sand, sharp limestone, and route-finding challenges across unmarked desert. Requires high-clearance 4WD with skid plates, recovery gear, and GPS navigation. Best tackled April through October when flash flood risk is minimal. No permits required but notify local ejido officials out of courtesy. Carry extra water and fuel—nearest services are 80 kilometers away in Saltillo. You’ll gain access to some of North America’s most significant paleontological sites while experiencing true Mexican desert solitude.

Frequently asked questions
Will a stock Tacoma or 4Runner handle this trail, or do I need a built rig?
A stock high-clearance 4WD with skid plates is the minimum — factory Tacoma TRD Off-Road or 4Runner Trail editions will manage, but skid plates are non-negotiable on the rocky desert hardpack. Lift helps on the rougher washes but isn't required.
What time of year should I avoid this route?
Avoid November through March — winter nights drop hard in the Coahuila desert and flash flood risk in the arroyos spikes after cold front precipitation. April through October is the window, with spring being the sweet spot before peak summer heat pushes into the high 90s°F.
Do I need a permit to run this trail or camp on ejido land?
The route crosses ejido communal land, which means you're dealing with local landowner permissions, not a federal permit system — stop and ask before camping on private ejido parcels. There's no formal fee structure, but a small voluntary contribution or asking permission in Spanish goes a long way with local ejidatarios.
What's the hardest section and what should I actually expect?
The toughest stretches are the eroded arroyo crossings through the fossil bed badlands — loose caliche over rock with off-camber approaches that'll test your lines. Nothing technically extreme, but one wrong read on a water crossing after rain turns a moderate section into a recovery situation fast.
How much fuel do I need to carry, and where can I resupply?
Plan for the full 112 miles with no resupply — the nearest reliable fuel is in Saltillo before you depart and there's zero cell service to call for help if you run dry. Carry a minimum 5-gallon auxiliary fuel can on top of a full tank; desert trail speeds and 4WD use burn more than you expect.
