Island Park, Idaho has "America's longest main street” and is located in the Snake River Highlands bordering Montana and Wyoming. The “main street” is 36 miles long. The breathtaking area is known for its rolling, pine-clad forests, and is an ancient volcanic Caldera. It's located between Ashton, Idaho to the south, and Montana state border to the north. Island Park is also located only 25 minutes from the West Entrance of Yellowstone National Park, at West Yellowstone, Montana.

Mack’s Inn Resort dates back to the early nineteen hundreds. The resort was established at its current location around 1914-1916 by William H. Mack. During the summer months, the Mack family focused on construction and expansion. Their winters were spent in the Snake River Valley planning for the next season.

For 75 years, Mack’s Inn continued to grow with more buildings, cabins and units. Then in 1989, a tragic fire destroyed the Mack’s Inn Lodge, a beloved landmark. The loss of the lodge was a great disappointment for the local residents and vacationers.

Mack's Inn was recently purchased by Ensign Hospitality, LLC in hopes to provide a new experience to travelers seeking an adventure. The goal is to build a new hotel that will blend in with the surroundings of Island Park, while still provided the resort experience Mack's Inn is known for.
