Hamdeok Seoubong Beach has shallow water and a fine white sand shore, and sits at the Seoubong entrance on the right side of Hamdeok Beach. Families swim and snorkel in the emerald water, and can walk the Seoubong trail and the coastal path. The Seoubong trail takes about one hour round trip, and a pavilion on the way up looks out over Hamdeok Beach and Hallasan. Canola flowers and green barley fields appear along the trail depending on the season, and trash is left on the beach when it is crowded.
