No ski lessons. No beginners allowed. All ungroomed terrain. Averaging 273 inches per year, Mount Bohemia is a snow-covered haven for seasoned skiers, eschewing bunny slopes for 500-plus acres with two chair lifts filled with 90 runs?most of which are rated for experts. The mountain's 900-foot vertical drop, noted for being the tallest in the midwest, has won it many fans, including MSN Travel, which named it on its list of 10 Undiscovered Ski Spots in 2006.
