Seoubong Dulle-gil is a hiking course next to Hamdeok Beach that connects to Jeju Olle Trail Course 19. A short climb from the gentle entrance brings Hamdeok Beach's emerald water into view, and rapeseed flowers bloom in season. The climb to the pavilion is easy, and the summit and the trail can be covered in under an hour. Past the pavilion, the many stairs make the difficulty rise sharply.
