For winter fun, four major ski areas are near Greenhouse at Fernwood. If you are a beginning skier, head for the small ski area on site and take a few lessons at the resort's ski school. It opens Dec. 26. Summer visitors can enjoy tennis courts and an 18-hole golf course, as well as a nine-hole executive course. Swim in the resort's indoor and outdoor pools or enjoy the beautiful national park bordering the Fernwood property.
