Which golf course in Jeju Island is the warmest? Except for Wooridul CC, which is located just south of Hallasan Mountain and is least affected by the harsh winter northwest winds, low-ying golf courses such as Crown, Shineville, Jungmun, St. Four, Raon, and Teddy Valley receive less snow and are warmer. Of course, there is no answer if heavy snow falls like yesterday and today...:) Common sense..
