I've been coming to Alta for over 20 years. It's a skiers paradise. Today was a powder day. I am happy that there are no boarders, but I am also disappointed in the skiers who throw things at the very nice employees who board backdrop Snowbird. They do not cause a problem really. The Peruvian is hot. Two outdoor hot tubs and one warm swimming pool, also outdoors. Not ski out, but experts can ski back, and the walk is not bad, and shuttle to the base is fine. Lively bar scene, and a movie every night. Who cares if there's no nightlife.
