About Arimo

Tucked into southeastern Idaho’s scenic Marsh Valley, Arimo offers a quiet, small-town pace surrounded by wide-open farmland and mountain views. With a population of around 350, it is the kind of close-knit rural community where neighbors know each other and life moves at a relaxed rhythm. Interstate 15 runs right past town, making it easy to enjoy the peace of country living while staying within an easy 35-minute drive of Pocatello for work, shopping, and healthcare.

Families in town are served by the Marsh Valley School District, with the local middle and high schools located right nearby. Daily life is low-key, centering around the local park, school sports, and exploring the outdoors. On weekends, residents can take a quick drive to Lava Hot Springs for swimming and soaking, head into the Portneuf Range for hiking and camping, or visit Pebble Creek for skiing in the winter. For anyone seeking quiet country living and mountain scenery with easy highway access, Arimo makes a welcoming home base.
