What's special

Heated attached garage

Wow, a lake house on 1.74 acres is a rare find in Wyoming, especially one that is set up to maximize outdoor living! Buy the home or buy the entire experience, as these owners are willing to sell their furnishings and some of their outdoor adventure toys like jet skiis, the boat, and the side by side. Inquire for a complete list of the amenities this property has to offer. Featuring 3 bedrooms and 2.5 baths, the views of Lake Desmet and The Bighorn Mountains are outstanding. Unique features include a hidden walk-in pantry in the kitchen, custom tiled shower in the master bath, a spacious wet bar downstairs for entertaining after a long afternoon on the boat, heated attached garage, and a detached shop with a full apartment. Multiple RV pads and hook ups. 4 boat lifts and a roll out Vdock.
