Vail Mountain is a giant that offers three different mountain skiing experiences for different levels of ability, and over 120 named trails. An enormous front face of long, smooth slopes is perfect for cruising, with runs for every level. For intermediates there is a wide variety of groomed runs, the longest of which is almost five miles (8km) long, from Flap Jack to Riva Ridge. The seven world-famous Back Bowls consist of miles of undefined open terrain and panoramic vistas, and are strictly for advanced and expert skiers, excellent on powder days. There are numerous beginners' areas as well as special family skiing areas around the mountains and a ski and snowboard school for learners or those wanting to advance to the next level. The resort reliably receives an average of about 27 feet (8m) of light powder snow each year.
