Keun Nokkome Oreum Observatory is in Sogil-ri, Aewol, Jeju. From the top, you can see a panorama of western Jeju and Hallasan, and in autumn you can also find eulalia grass. The climb passes a horse ranch and runs 2 km, with about 1.3 km gentle and 700 m steep. The final section is steep enough to require sneakers or hiking boots.
