Gwanggyo Marugil is a scenic walking loop around Gwanggyo Reservoir, mixing wooden decks, lakeside paths, and forested sections. It is a useful break from Suwon's historic core, with seasonal color from cherry blossoms, autumn leaves, and winter snow.
The trail is best as an easy half-day outing, especially for visitors who want a quieter nature walk without leaving the Suwon area.
