Kanab to Gardiner: Zion to Yellowstone Road Trip Guide

Driving from Kanab, Utah (elevation 4,970 ft) to Gardiner, Montana (elevation 5,282 ft) covers roughly 700 miles, tracing the spine of the Rocky Mountains. This route follows US-89 north through the Colorado Plateau, zigzags onto I-15 in Utah, then cuts east on I-84 and US-287 into Montana. The drive takes about 11-12 hours without stops, but you'll want to budget 3-5 days for the full experience. A key quirk: near Logan, Utah, US-89 squeezes through a narrow canyon where cell service drops for 20 minutes—locals call it the 'Bear Lake dead zone'.

Fuel economy matters on this long haul. Expect gas prices to vary: Utah averages $3.50/gal, Idaho $3.60, Montana $3.45. Plan refueling stops every 200 miles—key stations include Beaver, UT; Spanish Fork, UT; Tremonton, UT; Pocatello, ID; and West Yellowstone, MT. The highway is mostly well-maintained, but watch for frost heaves in Montana between May and October.

The North Entrance road is open year-round, but vehicle size restrictions (40 ft max) apply at the Roosevelt Arch.

The route passes two UNESCO World Heritage Sites: Zion National Park (near Kanab) and Yellowstone National Park (ending at Gardiner). Between them lies a tapestry of geology: pink sandstone cliffs in southern Utah, the Great Salt Lake's shimmering shoreline, the Caribou-Targhee National Forest's lava flows, and the Gallatin Range's rugged peaks. At mile marker 45 on US-89, look for the 'Candy Rock' formation—iron-stained sandstone that looks like striped taffy.

• Zion National Park (30 miles east of Kanab) – requires timed entry March-November
• Grand Staircase-Escalante National Monument – visible from US-89 near Kanab
• Bear Lake (US-89 near Garden City, UT) – Caribbean-blue waters, raspberry shakes at LaBeau's
• Yellowstone National Park (West Entrance via West Yellowstone or North Entrance via Gardiner)

Local commerce thrives around tourist corridors. In Kanab, grab a Navajo taco at the Rocking V Cafe. Near Bear Lake, raspberry milkshakes are mandatory—try the Bear Trapper. Montana's culinary scene features huckleberry everything: pancakes, syrups, and even huckleberry sausages at the Corral in West Yellowstone. For authentic bison burgers, head to the Buffalo Bar in Gardiner.

Road quality is excellent on interstates but patchy on two-lane sections. US-89 through Logan Canyon has sharp curves and occasional rockfall—drive 5 mph below the posted limit. I-15 near Salt Lake City can be congested; avoid 4-6 PM. Wildlife hazards: deer and elk frequent US-287 in Montana at dawn/dusk. Moose are rare but possible near Hebgen Lake.

• Family stops: Cornbelly's in Lehi, UT (corn maze, pumpkin slingshots)
• Pet-friendly stops: Ensign Peak Nature Park in Salt Lake City (leashed dogs on trails)
• Fatigue management zones: Rest areas at mile 105 on I-15 south of Salt Lake City, and at mile 4 on US-287 near Ennis, MT
• Hidden off-route spot: The Grotto Falls in Payson Canyon, UT (1.5-mile easy hike, dogs allowed)

Weather varies drastically. Summer (June-August): days 80-90°F, afternoon thunderstorms in mountains. Winter (December-February): snow possible from Logan northward; chains required in canyons during storms. Spring/Fall: 40-70°F, with blooming wildflowers (May) and golden aspens (September). Always carry water, snacks, and a paper map—cell service drops in canyons.
