The journey begins in Moab, surrounded by the red sandstone formations of Arches and Canyonlands National Parks. As you head north on US-191, the landscape transitions from desert scrub to the pinyon-juniper woodlands of the San Rafael Swell.

Entering Idaho, the terrain changes to rolling hills and farmland near Malad City. The final stretch along US-30 follows the Portneuf River through a narrow valley flanked by pine-covered mountains. Lava Hot Springs itself sits in a valley surrounded by the Portneuf Range. The town's main attraction is the naturally heated geothermal pools, a stark contrast to the cold river water.
