Seoho Park wraps around Seoho Reservoir on the western side of Suwon, giving the city a calm stretch of water, trees, and walking paths away from the fortress crowds. The reservoir is tied to King Jeongjo's 18th-century waterworks, and its evening view is counted among Suwon's traditional scenic spots.
Come for an easy walk rather than a major monument. The loop path works well if you want a quieter hour outdoors before returning to the old city walls.
