Circled by majestic mountains, this valley was a summer resort long before its skiing fame. Besides hiking, you’ll find golf, tennis, boating, swimming, and lift-assisted mountain biking, plus kids’ sports camps. Add summer music for adults and condo-style units at prices well below winter rates. Rates: from $166 (May 21–June 24) or $212 (June 25–Sept. 5) for a family of four, including all summer activities.
