Description

There is a rare sense of peace and privacy at 850 Fortress Road. A long private drive leads to a home surrounded by mature Douglas fir and pine, open land, and the quiet sounds of nature. Despite being only minutes from Big Sky’s shopping, restaurants, and amenities, the property feels worlds away from the activity of the resort. Here, the pace slows and Montana’s natural beauty takes center stage. Privacy is one of the defining qualities of this property. Open space protects the land across from the home, preserving the expansive view and open landscape. The neighboring lot was also intentionally acquired by the owners and a neighbor to create an additional privacy buffer. The result is a peaceful setting with very little surrounding development and a true sense of seclusion. The front porch is the heart of the property, overlooking the landscape and providing a front-row seat to Montana’s seasons. Mornings bring coffee and wildlife—deer in summer and elk in winter. Evenings offer sunsets, the calls of sandhill cranes, and hawks overhead, while the firepit provides the perfect place to gather. It is not unusual to watch bull elk spar from the property, and spring brings calves to the nursery pasture across the road. The approximately 3,875-square-foot home is thoughtfully arranged across three levels, with three bedrooms and three bathrooms—one on each floor for exceptional privacy. The main level features a warm and inviting open living, dining, and kitchen area with views toward the Spanish Peaks, along with a sunroom opening to a spacious back deck. The upper level offers a loft office and private primary suite. The lower level includes a bedroom and bath, family room, second kitchen, sauna, wine room, storage, and large patio—ideal for guests, entertaining, or additional living space. A beautiful guest cottage provides a sleeping area, living area, bathroom, porch, and campfire area. Above the garage, a partially completed space offers the opportunity to create a bonus room. 850 Fortress Road does not simply offer proximity to Montana—it feels like Montana. Mature forest, abundant wildlife, protected open spaces, privacy, adventure, and authentic Western character combine with convenient access to Big Sky to create a setting that is increasingly difficult to find.
