It is official. Sunday, June 3 will be the final day of the 2017-18 Season at Arapahoe Basin. Come on up and enjoy the final week. We have great Spring skiing. Lake Reveal has come to life. There will be live music in Mountain Goat Plaza Saturday and Sunday. The mountain goats are all over Little Lenawee Peak. And all kinds of fun and crazy A-Basin type stuff will be going on.
