Mack's Inn Resort
Our resort is the "Heart of Island Park" which is central to all activities. Located on Idaho State Highway 20 North and US Highway 191, access to Mack's Inn is convenient year around. Mack's Inn is just 20 minutes south of West Yellowstone the west entrance to Yellowstone National Park.
Mack's Inn is a vintage resort on the shores of the North Fork of the Snake River, just 5 miles downstream from Big Springs which is the headwater of the North Fork. This a natural stream that comes out of the mountain at 120 million gallons daily. The resort dates back to the early nineteen hundreds. It is a favorite spot for many family outings and family reunions.

Mack's Inn is located in the heart of Island Park on the banks of the Henry's Fork of the Snake River. The resort was located at its current sight around 1916 by William H. Mack or "Doc", as he was known by many. The Mack's used the summers in construction and expansion of the resort, while the winters were either spent in the Snake River valley or in California. In 1943, The Mack's Inn Lodge construction was started that year. In October of 1989, the Mack's Inn lodge, a landmark of Island Park, burnt to the ground. Although all of the lodging and convention facilities were not affected, the loss of the lodge was greatly felt by local residents and vacationers alike.
Island Park has "America's longest main street". The Island Park country is normally thought of as the rolling, pine-clad area between Warm River above Ashton to the south, and Henry's Lake to the North. Within the incorporated area lies a 35 mile "Main Street", over 75 miles of fishing streams, 2 lakes, and beautiful resorts. Island Park offers every kind of mountain recreation and every kind of accommodation to satisfy every kind of sportsman or tourist. Having a good time ranges from fishing and hunting, to horseback riding
A great virtue of North Fork fishing is the fact that it represents fishing for all ages, skills, and types of angling. Bait fishermen, and spinner-angleworm enthusiasts take their share in early season. Salmon-eggers do likewise in the numerous areas of the rivers and streams. The wet fly angler has perfect trout water in such areas as Box Canyon, Henry's Lake Outlet, and there is no more beautiful dry fly waters than the placid reaches of streams around Mack's Inn and Pond's Lodge, and the famed Railroad Ranch. Expert anglers, using the big flies as bait, enjoy a type of rainbow fishing found in few other localities.
