Susabong (Mulme Oreum) is a nature reserve next to Susan Reservoir in Jeju, a short oreum with black pine trees and a swing. From the swing at the entrance, the reservoir and Hallasan can be seen together, and the walk to the top takes 10 to 15 minutes. Parking at the large lot by Susan Reservoir leads directly up to the swing, and there is a restroom next to the parking lot. The summit is covered by trees, making it difficult to look down at the surrounding landscape.
