While studying abroad in Seoul, I was lucky enough to experience autumn in full swing in Yeongju. Hiking is an immensely popular pastime in Korea, and after spending a weekend in the mountains I can understand why. For a short hike, I suggest visiting the grounds of Buseoksa (부석사) Temple, if possible, before sunset! The temple is situated on top of a hill that overlooks the rest of Yeongju below. Our group had great timing because we were able to watch a drumming performance as the sunset on the temple grounds. Sobaeksan National Park (third photo) is another beautiful place to hike, though this will be an all-day adventure. The shortest hike to the highest point takes about 3 hours. For more info on this park: http://english.knps.or.kr/Knp/Sobaeksan/Intro/Introduction.aspx?MenuNum=1&Submenu=Npp There are plenty of other hiking opportunities in this area, including a rather treacherous trail that was more like a steep staircase (The credit goes to my friend Kayla for the photo!) Good luck on your exploration!
