Keystone Resort is more than a ski and snowboarding destination, it's an adventure. It's more than a place; it's a way of life that compels everyone to try something new and discover their favorite Rocky Mountain adventure. Keystone Resort was founded November 21, 1970 by Max and Edna Dercum. Their passion, vision and commitment is found throughout the resort. From the early days, Keystone was known as an adventurous place where people came to be with friends and family. We still hold these principles true.
