Mammoth Mountain

We're California's leading four-season mountain resort operator, welcoming guests to experience the Eastern Sierra's legendary playground at 11,053 feet. Founded by Dave McCoy in 1953, we've grown from a humble ski area into a destination that spans 3,500 acres of skiable terrain, 25 lifts, and 178 trails that cater to everyone from first-timers to seasoned experts. Our winters bring some of the most reliable snow in the country - averaging 400 inches annually - while our summers transform the mountain into a world-class bike park with over 80 miles of single-track trails.

Beyond the slopes, we operate a collection of lodging properties including Juniper Springs Resort, The Village Lodge, and The Westin Monache, plus our network of retail shops that have been outfitting mountain adventures since our earliest days. We're proud to be part of the Alterra Mountain Company family, which connects our pass holders to destinations across North America. What really drives us is creating genuine mountain experiences - whether that's a family's first ski vacation, a spring session in our legendary terrain parks, or a summer day exploring the alpine landscape. We're not just in the business of skiing or biking; we're in the business of helping people build lasting memories in one of the most spectacular settings on Earth.
