Utah BDR Central Segment — Salina to Hanksville via the San Rafael Swell and Factory Butte
Canyon country, a river ford, and alien badlands.
This segment of the Utah Backcountry Discovery Route drops south from Salina through Salina Canyon before swinging east across the San Rafael Swell — a massive geological upwarp of Navajo sandstone, Entrada slickrock, and slot-canyon drainages that most drivers only see from I-70 at 75 mph. The route threads through Mexican Mountain Road, crosses the San Rafael River ford near Fuller Bottom, and pushes south through the Wild Horse Mesa country before arriving at the Factory Butte clay badlands just north of Hanksville — a genuinely alien landscape of stripped bentonite domes and clay flats that turns impassable within minutes of rain. Key waypoints include Goblin Valley State Park access and the Black Dragon Canyon pullout.
The San Rafael River crossing at Fuller Bottom is the crux — it’s typically shallow but wide, with a soft sandy bottom that will swallow a vehicle if you hesitate. After rain, the clay sections around Factory Butte become axle-deep mud traps with zero warning. You need high clearance, a locker or at minimum a good limited-slip, and a recovery kit. Fuel in Salina before you leave and top up in Hanksville; there is nothing between them on this route. Cell service drops out east of I-70 and stays gone. Best season is April–June and September–October. No permit required on BLM sections; Goblin Valley State Park has a day-use fee.

Frequently asked questions
Can a stock 4Runner or Wrangler run this segment without modifications?
A stock high-clearance 4WD can get through, but a locker — front or rear — is strongly recommended for the rocky San Rafael Swell sections and the Muddy Creek ford. Skid plates and at least 32-inch tires will save you headaches on the shelf roads and ledge rock.
When is this segment passable, and what shuts it down?
April–June and September–October are the sweet spots. Summer heat in the canyon country and Factory Butte badlands is brutal and can push 110°F, making mechanical problems genuinely dangerous. Winter snowpack above 6,000 feet and flash flood risk in the Swell's slot canyons during monsoon season (July–August) are the two biggest closers.
Do you need a permit to run this segment?
No permit required for vehicle travel on the route itself — it crosses BLM land managed by the Price and San Rafael Desert Field Offices. Some developed campgrounds in the Swell charge a small fee, but dispersed camping along the route is free. Check current fire restrictions with the BLM Price Field Office before you go, especially in summer.
What's the hardest section and what does it actually throw at you?
The Muddy Creek crossing is the most committing obstacle — it's a true river ford with soft, silty bottom and no bridge; depth varies with season and recent rain. The rocky ledge and shelf road sections through the San Rafael Swell require precise line choice and will punish low-clearance rigs. Neither section is impossible, but both demand a confident driver and a mechanically sound rig.
How far is the nearest gas from the route, and how much range do I need?
Salina has fuel at the start and Hanksville at the end — there is nothing in between for the full 148 miles. Carry a minimum 5-gallon fuel reserve; slow technical terrain, sand, and elevation change will spike your consumption. Do not count on topping off anywhere mid-route.
