One of Colorado's biggest and most popular mountains, Vail, is opening today for skiing at 9:00 am. The map above highlights what snow lovers will have access to this morning, with opening day lifts highlighted in yellow and available terrain marked in green. Vail will open with 540 acres of terrain and 7 lifts operating out of both Vail Village and Lionshead, all on the frontside of the mountain. Don't miss free breakfast burritos and hot chocolate for the early risers, and the Red Bull DJ truck will be spinning tunes at the base.
