Last time I was at Norris, I want to say i could get anywhere I wanted to go on the lake within about an hour/hour and a half and i was staying on the far NW tip of the lake, which I must say is the best place for riding on the whole lake.
It is before you get to flathollow up the powell and it will take you about 35 minutes to get to stardust. When are you coming down. Make sure you come back to the pro shop when you get there, just follow the signs to Norris Wake. And we also have bands every Saturday if you are coming for a weekend.
