Brief History
Island Park’s history is deeply intertwined with the geological forces that shaped the region. The area sits within the Island Park Caldera, formed by massive volcanic eruptions over a million years ago. Native American tribes, including the Shoshone and Bannock, were the first to inhabit this region, using it as hunting grounds for centuries.
European explorers and fur trappers began to frequent the area in the early 19th century. The completion of the Oregon Short Line Railroad in the late 1800s brought more settlers and visitors to the region, drawn by its natural resources and beauty.
Island Park was officially incorporated as a city in 1947, primarily to allow the sale of liquor in the area, as Idaho had strict liquor laws at the time. The city’s unique shape – a narrow strip 500 feet wide and 33 miles long – was designed to encompass the area’s lodges and resorts.
Throughout the 20th century, Island Park developed into a popular destination for outdoor recreation, particularly fly fishing and, later, snowmobiling. Its proximity to Yellowstone National Park has also played a significant role in its growth as a tourist destination.
