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 Resort was recently purchased by Island Park Hospitality, LLC to provide travelers with a higher standard experience in a remarkable corner of the world.  Ensign Hospitality, LLC will develop and manage the new hotel and resort.  The resort will aesthetically blend with the unparalleled natural beauty of Island Park.  If you are new to Island Park or have been coming for years we hope to see you at Mack’s Inn Resort.
