Taegisan Mountain in Hoengseong has a wind power plant, creating a unique landscape. In winter, the snowy scenery created by snowflakes is at its peak. The summit of Taegisan Mountain is inaccessible due to military facilities, but you can enjoy the spectacular view from the Taegisan Observatory next to it, so many people visit to take the shot of a lifetime. The course that goes up the forest road from the entrance to Yanggudumijae is flat and takes about 3 to 4 hours, making it an easy hike to enjoy, making it a popular destination for tourists all year round. It used to be accessible by car, but now car entry is restricted.
