Ski along scenic slopes at Galena's Chestnut Mountain Resort, perched high above the Mississippi River. Rated by Ski Magazine as one of the top ski resorts in the Midwest, Chestnut Mountain goes all out with a snowboarding park and night skiing. Stay at the rustic 120-room lodge, which has three restaurants, including the fine-dining Sunset Grille. There are fun non-skiing activities in the summer as well, including boat cruises on the Mississippi Explorer and the exhilarating Alpine Slide, which speeds 2,000 feet down a hillside. Or try the new Segway Mountain Adventure Tours, a three-mile guided ride through rolling terrain.
