Season Info

While most resorts wind down in spring, A-Basin often continues operations into early summer, sometimes as late as July 4th. The mountain typically opens in October, offering one of the first chances to ski in Colorado each season. High elevation and favorable weather patterns create exceptional snow conditions throughout an extended season that can last up to 8 months.
