We usually drive up to Bedřichov, and ski from the Maliník parking lot. My advice, get there early. We took a vacation day one Wednesday to try to beat the parking lot crowd, arrived at 10, and snagged the last space in the lot. Once you're on the trails though, it's not crowded at all (there's enough space for everyone when you have so many kilometers to choose from!).
Here are pictures from one of our treks last year. Tempting isn't it?
