Santa Barbara to Hanksville: Epic Desert Road Trip

Did you know that the route from Santa Barbara to Hanksville crosses the San Andreas Fault near the Grapevine, then passes through the Mojave Desert where temperatures can exceed 120°F in summer? This 700-mile journey takes you from the Pacific coast to the red rock canyons of Utah. The drive typically takes 11–12 hours without stops, but you'll want to allocate at least 3 days to explore the highlights.

Starting on US-101 north, you'll transition to I-5 over the Tejon Pass, then join I-15 through the Mojave. After Las Vegas, you'll take I-70 east to UT-24, which leads directly to Hanksville. This route offers dramatic shifts in climate, landscape, and culture. For more on how to find the best stops and hidden gems between cities, check our guide.

Fuel stations are plentiful along I-15 and I-70, but sparse on UT-24 between the I-70 junction and Hanksville — only one station at Caineville (45 miles west of Hanksville). Plan to fill up in Richfield (exit 56 on I-70) or at the I-70/UT-24 junction. Gas prices rise significantly in remote areas. For electric vehicles, Superchargers are available in Santa Barbara, Tejon Ranch, Barstow, Las Vegas, and Richfield. No chargers exist between Richfield and Hanksville (130 miles).

• Estimated fuel cost ($4/gal): $100–$130 for a 25-mpg car.
• Best fuel stops: Barstow (cheapest on I-15), St. George (UT), Richfield.
• Restrooms: Rest areas at Grapevine, Baker, and near Beaver.

The route traverses four distinct ecosystems: coastal chaparral, high desert, Mojave scrubland, and Colorado Plateau sandstone. Notable landscapes include the San Rafael Swell (a 40-mile-wide anticline visible from I-70) and the multi-hued cliffs of Capitol Reef. Off-route: take UT-24 detour to Goblin Valley State Park (5 miles south of UT-24) for hoodoos. Another hidden gem is the Mars Desert Research Station (on Cow Dung Road, 20 miles west of Hanksville).

Local commerce along UT-24 includes small trading posts selling Navajo rugs and pottery near Caineville. In Hanksville, the Hollow Mountain Gas Station—built into a sandstone cliff—sells local honey and sarsaparilla. For authentic western memorabilia, visit the Hanksville Trading Post (est. 1882).

Road quality is excellent on Interstates, but UT-24 west of Hanksville is two-lane with occasional rough patches. Wildlife (mule deer, cattle) roam at dusk; drive cautiously. Cell service is spotty on UT-24—download offline maps. Summer heat requires extra water. Family-friendly stop: Crystal Springs (exit 62 on I-15) has a pirate-themed water park. Pet-friendly: rest areas along I-15 have dog runs; Jaker's on I-15 in Parowan offers a pet menu.

To combat fatigue, take breaks every 2 hours. Ideal rest zones: Rest area at Baker (NV) (mile 272 on I-15) has shade and picnic tables; Cove Fort (exit 100 on I-70) has a historical site. For overnight stays, consider Richfield (chain motels) or Hanksville (economy motels, no national chains).
