Tahoe Donner Downhill Ski Area is owned and operated by the Tahoe Donner Association, and offers 120 skiable acres of beginner and intermediate terrain.
If you like to ride your bike downhill, on great trails, then you want to ride Downieville Downhill. And if you’re going, the best thing to do is get a shuttle ride to the top. Yuba Expeditions offer daily shuttles (book in advance!), and have demo bikes plus all the gear and supplies you’d need.
