What's special

Prettiest drainagesPrivate road

The Montana Wishlist! This property situates in one of the prettiest drainages between Gallatin Gateway and Big Sky-----Little Bear. This area is highly coveted, worldwide, as is exemplified by the local land ownership. This quaint little homestead is nestled on 5 beautiful acres just above the confluence of Little Bear Creek and Big Bear Creek. The property is served by a shared private road with 7 Ranges and remains very private. The ranch home is modest but could be fixed up or used as a guest home or a manager's quarters. Come enjoy the beauty and privacy of Little Bear!
