A steep, 20-minute walk up the south face of the craggy Sanbang-san is a stone Buddha in a 5m-high cave called Sanbanggul-sa. From Sagye-ri, the walk up looks more daunting than it really is, but after reaching the cave you'll be delighted because of the powerful 'wow' factor. Lower down, by the ticket office, are more-modern shrines and statues.
