Sangumburi CraterSangumburi is a vast crater—some 650 meters wide—that sits to the east of Hallasan. The area has been named a national monument and the fact that it isn’t as popular as the more famous Sunrise Peak means it’s easier to escape the crowds here. The crater is overgrown with a diversity of plants, from silver grass to magnolia trees and rare winter strawberries. The astounding number of plant species in such a small area has made the crater not only a popular destination for travelers but of interest to botanists as well.
