Gunstock Mountain Resort. High above Lake Winnipesaukee, this ski resort has invested millions to increase snowmaking capabilities, introduce more options for beginners, and add slope-side dining. Thrill Hill, a snow-tubing park, has five runs, a lift service, and 21 acres of terrain parks. The ski area has 55 trails (24 of them open for night skiing) and 32 miles of cross-country and snowshoeing trails. In summer, the Mountain Adventure Park offers an adrenaline rush with ziplines, an aerial obstacle course, and scenic chairlift rides. There are also trails for mountain biks, a skateboarding park, and paddleboats. 719 Cherry Valley Rd., Gilford, NH, 03249. 603/293–4341. www.gunstock.com.
