World’s Largest Mountaintop Snow Fort returns to Keystone for the 2022-23 season

The World’s Largest Mountaintop Snow Fort has opened at Keystone Resort, and they celebrated its return in style with a festive grand opening ceremony and fireworks display atop Dercum Mountain on December 23.

Sitting at an elevation of more than 11,600 feet, with a 10,000-square-foot footprint and reaching heights of more than 30 feet tall, the World’s Largest Mountaintop Snow Fort lives up to its name. And this year, the Snow Fort returns to the top of Dercum Mountain with brand-new features and designs, including a frozen spiral slide, an ice cave, ice carvings and fun for guests of all ages.

The Snow Fort is now open daily and will remain open throughout the winter season for as long as the snow lasts. The World’s Largest Mountaintop Snow Fort was constructed by Snice Carvings LLC with support from Keystone’s Snowmaking and Mountain Operations department. The fort took approximately two weeks to construct. You can learn more about the building and creation of the Snow Fort in this video. 

But, that’s not all. This year, Keystone is doubling the fun with a second Snow Fort experience in the Mountain House Base Area. With this new fun zone, kids will be able to play in the snow while parents pop into the nearby Last Lift Bar for après. Look for a second Snow Fort Experience to open in the early new year.
