As kids, we dreamed of building tree houses big enough to live and play in. Today, thanks to Airbnb, such a tree house exists. Located in Glacier National Park is this 500 square foot tree house. A spiral staircase wraps around a giant Douglas fir tree and leads you into the main living area. There are 2 outside deck areas featuring gorgeous views of the surrounding lakes, mountains and forests. There is a full kitchen, dishwasher and stove as well as a bathroom with full sized shower and toilets. The master suite has a comfortable queen mattress and additional sleeping quarters in the common room accommodate up to 4 guests. For activities, there is Whitefish Mountain Ski Resort, Flathead Lake, and plenty of fishing, rafting, boating, hiking and more Montanan adventures.
