Seoraksan National Park's Seorak-dong district sits in Sokcho. The Ulsan Bawi and Biseondae walking paths can be covered together. The route from Osaek Mineral Spring through Daecheongbong and Gongnyong Ridge to Biseondae is 16km and takes 10 hours 30 minutes. Because it is a long course, going with only a light walk in mind puts a strain on you.
