Idaho Falls to Winslow Road Trip: Epic Scenic Drive Guide

The 883-mile drive from Idaho Falls, Idaho to Winslow, Arizona along US-20 and US-89 traces the path of early Mormon pioneers and the Old Spanish Trail. This route crosses the Continental Divide at 7,900 feet near Monida Pass, a milestone where water flows either to the Atlantic or Pacific. Estimated driving time is 14 hours without stops, but the journey demands at least two days to fully experience the geothermal wonders, red rock canyons, and Navajo cultural sites.

We recommend splitting the drive in two: first day from Idaho Falls to Salt Lake City (about 3.5 hours), then on to Winslow on day two (about 8 hours). This pacing allows exploration of the best stops between Idaho Falls and Winslow without exhaustion. The route is worth every mile for those seeking dramatic geological transitions from volcanic plains to slickrock deserts.

The primary route uses US-20 West from Idaho Falls to US-89 South through Utah, then I-15 briefly near Salt Lake City before rejoining US-89 and finally US-160 into Winslow. Fuel stations are abundant along Interstates but become sparse between Moab and Bluff (a 100-mile stretch with only one station in Monticello). Check your tank at Moab before heading south.

• Best fuel stop: Fill up at the Sinclair in Blanding, UT (mile 650) before the final push into Arizona.
• Diesel: Many stations in small towns offer diesel, but confirm availability in Mexican Hat, UT.
• EV charging: Tesla Superchargers in Idaho Falls, Salt Lake City, Moab, and Flagstaff. Level 2 chargers at some hotels.

Road quality is excellent on Interstates, but US-89 south of Kanab has winding sections with steep cliffs. The section through Monument Valley on US-163 is a gravel road in parts; check conditions if recent storms. Winter driving from November to March requires snow tires from Idaho Falls through Salt Lake City; south of Moab, snow is rare but possible.

Tolls: None on this route. Speed limits: 75 mph on Interstates, 65 mph on US highways, 55 mph in construction zones. Watch for wildlife (deer, elk, cattle) from dusk to dawn, especially in rural Utah.

Infrastructure Safety and Road Quality

• Road conditions: Check UDOT Tracker (Utah) and ADOT (Arizona) for closures.
• Emergency services: Cell service is spotty in remote stretches; carry a satellite communicator if off-roading.
• Gas station safety: Use well-lit, busy stations at night.

Fatigue Management and Rest Zones

• Rest areas: Every 60-80 miles on Interstates; clean but basic. Notable: Portage Rest Area (near Idaho border) and Scipio Rest Area (Utah).
• Recommended sleep stops: Salt Lake City (Midvale area) or Moab for night one; Blanding or Kayenta for night two.
• Driver fatigue warning signs: Long straight stretches west of Blanding are hypnotic – stop every 2 hours.
• Caffeine stops: Dutch Bros Coffee in Idaho Falls, Rockwell Coffee in Moab.

Family and Child Suitability

Pet-Friendly Framework

• Pet policies: Leashed pets allowed in national parks on developed roads and campgrounds, but not on trails or in buildings.
