Nestled on seven wooded acres at the gateway to the Glacier National Park, the Montana Treehouse Retreat reimagines our childhood hideout. A spiral staircase leads to the two-story cabin. Perched on two live trees, the interior consists of a full kitchen, a living space, and a master suite arranged around the trunks. Each level opens out to an exterior deck overlooking the forest setting. While the house is an adventure of its own, the nearby Whitefish Mountain Ski Resort and Flathead Lake can add a host of other activities to the agenda.
