Muju ski and snowboard resort is just an hour an a half drive from Jeonju. During the season, which runs from early December until May there is a daily coach service which picks up at Geaksa house and opposite the large hospital on the main road in Ah Jung Lee. Its a real bargain with transport there and back again, hire of all of you equipment and an all day lift pass costing just 70,000 won.
Muju resort is widely thought to be the best ski resort in Korea and has everything you would want. Try and go on a weekday if possible to avoid the crowds.
