Aspen Mountain, the mothership, rises above Aspen and anchors the town as an alpine skiing village. It was the first mountain developed, putting Aspen on the map as a ski resort, and perhaps the most notorious of Colorado ski resorts. Commonly referred to as Ajax, Aspen Mountain does not have any green circle or beginner runs.
For the 2023/2024 winter season there is more terrain to explore on Aspen Mountain. The new Hero's terrain and a new high-speed quad will offer an additional 153 acres of fresh snow to explore. This marks the mountain's first significant addition since the inauguration of the Silver Queen Gondola in December 1985.
