Island Park, Idaho

Some of the same natural forces that once made Yellowstone National Park so scenic also made Island Park similarly beautiful. Island Park sits in the world’s largest caldera, 23 miles in diameter, created from a volcano that collapsed in prehistoric times. Now covered in a dense forest of pine and wildflowers and an abundance of wildlife. We invite you to explore all Island Park has to offer.
