Skiing and Snowboarding
The mountains around Lake Tahoe are bombarded by blizzards throughout most winters and sometimes in fall and spring; 10- to 12-foot bases are common. Indeed, the Sierras often have the deepest snowpack on the continent, but because of the relatively mild temperatures over the Pacific, falling snow can be very heavy and wet—it's nicknamed "Sierra Cement" for a reason. The upside is that you can sometimes ski and board as late as May (snowboarding is permitted at all Tahoe ski areas). The major resorts get extremely crowded on weekends. If you're going to ski on a Saturday, arrive early and quit early. Avoid moving with the masses: eat at 11 am or 1:30 pm, not noon. Also consider visiting the ski areas with few high-speed lifts or limited lodging and real estate at their bases: Alpine Meadows, Sugar Bowl, Homewood, Mt. Rose, Sierra-at-Tahoe, Diamond Peak, and Kirkwood. And to find out the true ski conditions, talk to waiters and bartenders—most of them are ski bums.
The Lake Tahoe area is also a great destination for Nordic skiers. "Skinny" (i.e., cross-country) skiing at the resorts can be costly, but you get the benefits of machine grooming and trail preparation. If it's bargain Nordic you're after, take advantage of thousands of acres of public forest and parkland trails.
