During most of the year, Immigrant Road is a well-maintained gravel road that is easy to drive and can be driven in any vehicle. However, there is no winter maintenance, so it can be dicey to drive during the winter. The west half of the road is mostly straight and runs along the foothills of the Bennett Mountains. The east half of the road runs through part of the Bennett Mountains; this section has significant climbs that twist and turn up and down the grades.
About midway along the road is an information board describing Kelton Road, Site 6 of the Main Oregon Trail Backcountry Byway. Kelton Road was a popular freight route bringing goods from the Transcontinental Railway at Kelton, Utah, up to Boise, Idaho.
Although dispersed camping is allowed on public lands bordering Immigrant Road, there are no obvious places to set up. Two sections of private land should be avoided if you decide to camp.
