Tips for This Route
Stop at Twin Falls for more than fuel
Twin Falls sits right along the Snake River canyon, and Centennial Waterfront Park offers a playground, picnic shelters, and bathrooms with canyon-edge views. Let the kids play while you stretch, then grab coffee at Maui Wowi nearby before getting back on I-84.
Watch for truck traffic on I-84
The I-84 corridor between Boise and the Utah border is a major freight route. Heavy truck traffic is worst on weekday mornings and through the Declo-to-Snowville stretch where the road narrows in spots. Stay alert and give semis plenty of space.
Prepare for elevation changes near Snowville
I-84 climbs through the Raft River range near the Idaho-Utah border before descending into Tremonton. Winter weather can close this stretch quickly. Even in fall and spring, carry warm layers and check road conditions on 511.idaho.gov.
