Hike up 30 minutes behind Seonun-sa to this giant Buddha rock carving dating to the Goryeo dynasty; the amazing image is carved into the cliff face and is 15m high. On the right is a very narrow grotto, and next to it stairs lead up to a tiny shrine and a great view.
From the Buddha, you can climb Nakjodae and carry on up to the lookout at Gaeippalsan, with views of the West Sea, before heading back down to Seonun-sa.
