Huge Mountain, Easy to Get Around, Great Snow
Expensive Lodging, Frequent Wind Hold
I've been all over California snowboarding (all of the Tahoe resorts, Big Bear, Mt. High, etc), and Mammoth is by far the best resort in the state. Although Heavenly says it is the biggest resort in CA, I've been to both and Mammoth has more actual accessible terrain than Heavenly could dream. This place has more express lifts than I think all of the resorts in Tahoe combined. Also, there is so much variety, anybody from a new skier all the way to the hardest core skier or rider, will have a blast with tons of terrain of all levels.
As a SoCal resident, I've found my home resort.
