Samgaksan Mountain is a mountain situated on the northern outskirts of Seoul, resembling a folding screen. Its name, meaning triangular mountain, is derived from the presence of three high peaks: Baegundae Peak, Insubong Peak, and Mangyeongdae Overlook. The highest peak, Baegundae Peak, offers a panoramic view of Seoul from its summit, featuring a spacious rock surface where many visitors can sit. Positioned behind Gyeongbokgung Palace, the palace of the Joseon dynasty, Samgaksan Mountain is visible from the rear of the Cheong Wa Dae.
