This remarkable mountain community represents one of America’s most unique residential areas. Stretching 33 miles along Highway 20 yet only 500 feet wide in most places, this incorporated city claims the distinction of having the world’s longest Main Street. The community’s fascinating history dates back to 1947 when lodge and resort owners incorporated primarily to circumvent Idaho’s liquor laws, creating what would become one of the state’s most distinctive municipalities.
The demographics tell the story of a community that attracts successful, established residents seeking a mountain retreat. With a median age of 67 years and a median household income of $74,750, this is a mature, affluent community where quality and craftsmanship are highly valued. The population of approximately 190 residents creates an intimate, close-knit atmosphere while the geographic layout provides unparalleled privacy and space.
What makes this location truly special is its position within the Henry’s Fork Caldera, a massive volcanic formation that creates the unique topography and stunning natural setting. This caldera, formed by the same geological forces that created Yellowstone, provides the dramatic landscape of meadows, forests, and waterways that define the area’s character.
The community’s connection to outdoor recreation is unmatched. Henry’s Fork of the Snake River, flowing directly through the area, is ranked by Trout Unlimited as the number one trout stream in America. Henry’s Lake to the northwest provides additional world-class fishing opportunities, while the extensive trail system connects residents to over 500 miles of groomed snowmobile routes during winter months.
For families and outdoor enthusiasts, the proximity to educational and cultural opportunities enhances the area’s appeal. Brigham Young University-Idaho in Rexburg is just 53 miles away, while Montana State University in Bozeman provides additional higher education access within reasonable distance.
World-Class Fishing: Henry’s Fork of the Snake River runs directly through the community, providing residents with front-door access to what many consider the finest trout fishing in America. The river’s spring-fed waters maintain a constant 50-degree temperature year-round, creating ideal conditions for rainbow, brown, and cutthroat trout.
Winter Sports Capital: With an average annual snowfall of 215 inches and elevation of 6,300 feet, Island Park transforms into a winter wonderland. The extensive groomed trail system connects to West Yellowstone, creating what many consider the finest snowmobiling network in North America.
Mesa Falls Access: Just minutes away, Upper and Lower Mesa Falls represent two of Idaho’s most spectacular waterfalls, with the Upper Falls dropping 105 feet through a narrow canyon carved by the Henry’s Fork River.
Yellowstone Gateway: Living here means unlimited access to Yellowstone National Park’s west entrance, just 15 miles away. Residents enjoy the park’s attractions without the crowds, with easy access to Old Faithful, wildlife viewing, and the extensive Yellowstone ecosystem.
Henry’s Lake: This high-mountain lake, surrounded on three sides by the Continental Divide, offers exceptional fishing for cutthroat, rainbow, and hybrid trout. The lake’s scenic beauty and pristine waters make it a favorite for both recreation and peaceful contemplation.
Harriman State Park: Known as “the Ranch” to fly fishing enthusiasts worldwide, this 16,000-acre preserve offers 24 miles of groomed trails perfect for hiking, cross-country skiing, and wildlife viewing in a protected ecosystem.

We just moved into our new home we built with immaculate!! We absolutely love it! We worked with Anna and she made building a home so much easier! They were ALWAYS available to answer questions, concerns, and give me progress updates. If I ever wanted to change something she was very upfront with the cost, time frame and ability to do so. Very open and honest, and we love our new home! I would definitely build with them again! Thank you immaculate for everything!
My family was living overseas for the military when we decided to move to Providence. Anna Christensen was always available and took care of all of the bumps along the way. Her availability and responsiveness was what sold me most. When we finished the home we had an independent inspector come by and look at the home. When he asked who built the home, we mentioned Immaculate and he said, “Oh good, they build very good homes and never skip steps.” Of all the reviews I read and heard, his meant the most to me as I want to stay in this home for a long time! If you are military I recommend Immaculate! They won’t hide poor quality even if you are unable to inspect it yourself and they will ALWAYS respond and reply with the myriad of questions I guarantee you will have.

Built a beautiful home with Immaculate in 2012. They were great to build with and knew what we wanted and made it reality even though it was a bit different than the norm. Then after the home was finished and moved in they continued to stand behind their work. We then sold that house about a month ago and during the due diligence the buyers had a home inspection. The home inspector found zero issues with the house and highly recommended the buyers to buy the house. He said that rarely happens so that goes to say that they build a quality house. Now we are in the process of designing a new home with Immaculate and looking forward to making our vision a reality again.
We had such a positive building experience with Immaculate Construction! They helped me pick colors, presented me with a variety of design options and helped me stay on budget! I highly recommend building with Immaculate! We love our new home!
We have been in our home for 6 months now. We are still in amazement we live here. Every day we talk about how much we love living here and coming home. The entire staff was excellent and have made it an amazing experience. To say they went above and beyond our expectations is a fair statement. Our home is so beautiful, it is as amazing as Anna first described and its built as well as Jordan told us it would be. They kept saying “it will look like you want just be patient”, whenever we had a concern. Great experience, great response after moving in and having questions even if it was already explained. Very grateful and appreciative for our forever home!
