Places in Eastern Idaho

Understand

This area is characterized by the seemingly interminable flat expanse of the Snake River Plain to the west and the gradual incipient rugged terrain of the Rockies to the east that will reach a crescendo in the Grand Tetons as you cross the Wyoming state line, with a pocket of forest in the northeast corner. The region was largely settled by Mormons who persevered against the harsh climate and rigors of untamed land to create their agricultural and religious communities.

Cities

  • Ashton — well-known for its seed potato growing area
  • Driggs — a relatively small town in the Teton Valley that features great views and year-round outdoor activities
  • Idaho Falls — a destination for adventure sports
  • Island Park — a city that is 500 feet (150 m) wide in most locations and 33 miles (53 km) long, it claims to have the longest main street in the world
  • Rexburg — a base for exploring the St. Anthony Sand Dunes, the West Entrance of Yellowstone National Park, and the Grand Tetons
