Yangsan Singi-dong’s Seonang Fortress ruins sit on a low ridge, offering quiet hilltop panoramas over Gyeongsangnam-do’s patchwork landscape. Best in spring/fall for crisp air and layered ridgelines; winter can bring dramatic sky contrast. The site is lightly touristed, great for sunrise/blue-hour atmospheres and archaeology-meets-landscape compositions.
