Inside Big Sky’s New Explorer Gondola and Kircliff Observatory

The 'Big Sky 2025' transformation is completed, cementing Big Sky Resort as home to North America’s most advanced lift system. On December 20, 2025, the resort unveiled its final two upgrades: the Explorer Gondola and the Kircliff Alpine Observatory. These projects are the 13th new lift project in 10 years and reimagine the journey from the valley to Lone peak.

Replacing the Explorer chair, the last of the resort’s original infrastructure, is the new Explorer Gondola. This high-speed, two-stage system is now the fastest 10-person gondola in the world, whisking guests toward the Bowl at speeds of 7.1 meters per second for a total of a 9-minute ride.

The cabins are designed for ultimate comfort, with floor-to-ceiling panoramic windows and heated seats. For beginners, the gondola’s mid-station provides an new learning zone with dedicated trails and magic carpets.

Perched at 11,166 feet atop Lone Peak, the Kircliff Alpine Observatory offers an experience unlike anything else. This architectural construct is perched over the mountain's edge and features an all-glass enclosure.

On clear days, visitors can see, Montana, Idaho, and Wyoming, and two national parks, Yellowstone and Grand Teton. The most exciting feature is the glass floor, allowing guests to peer directly down the fall line of Lone Mountain.

Reaching the summit of Lone Peak required advanced ski skills or a serious hike previously. With the completion of the Explorer Gondola and its seamless connection to the Lone Peak Tram, the peak is now accessible to foot passengers for the first time in winter history. The entire journey from the base area to the clouds takes just 15 minutes.

This milestone marks the steps to turn Lone Peak into a year-round, world-class destination where architecture and alpine culture meet.
