The Yukdam waterfall and the Biryeong waterfall (비룡폭포) are located on the left side of the valley, about a forty-minute walk from the main car park. Ulsanbawi (울산바위) is a rock formation in the Seoraksan national park. The shape of Ulsanbawi is unique in the area. To reach the rocks you need to follow a hiking path and climb over 800 steps (it is actually 888 steps according to locals). On the way there, there are two temples and a spherical rock (Heundeulbawi, 흔들바위) which is located on top of a larger rock. This rock is about 5 meters (16 feet) high and can be moved with some effort. Thousands of people have already tried to push down Heundeulbawi, but nobody gets further than waggling the rock.
