Cheonbuldong Valley is a waterfall valley in the Oeseorak section of Seoraksan in Sokcho, running from Biseondae toward Daecheongbong. Gwimyeonam, Oryeonpokpo, Yangpok, and Cheondangpokpo follow one another among odd rocks and clear water. The once rough path is now linked by a cliff walkway and deck stairs. The climb is not easy, so beginners need to choose their hiking route carefully.
