수산저수지

Susan Reservoir is a public reservoir in the Jeju Island area, set up as a regional water-supply infrastructure that has matured into a quiet lakeside walking destination. The reservoir spans a moderate area of open water surrounded by Jeju's distinctive temperate-to-subtropical landscape, with a walking-and-cycling path that loops the reservoir shoreline. The combination of the open-water surface, the surrounding Jeju landscape, and the quiet atmosphere — far less visited than Jeju's headline coastal destinations — gives the reservoir a distinctly contemplative character. Best for travelers seeking a quieter inland Jeju experience away from the busier coastal tourism corridors, particularly for slow-walking and birdwatching opportunities. Pairs naturally with broader inland Jeju itineraries.
