Ulsan Bawi Course -- This course is relatively easy from Heundeul Bawi (Teetering Rock) to Gyejo-am. The difficulty comes in the steep climb up the rocks of Ulsan Bawi from the hermitage below. There are metal stairs to help with the climb, but it's still quite dangerous and slippery, especially in wet weather. Still, the view of the mountains and the ocean from the top is worth all that hard work.
