Sinseonbong (Sinseondae) in Seoraksan, Inje, is a nature protection area. From the ridge, Ulsanbawi forms the backdrop for views of the Dinosaur Ridge and the sea of clouds. The climb takes 1 hour 40 minutes from Yangpok Shelter and 5 hours from Sogongwon. Gusts blow across the ridge, and fallen leaves and gravel make the footing slippery.
