Semiwon is an aquatic plant garden in Yangsu-ri, Yangpyeong, on the northern edge of Paldangho Lake, where lotus, water lilies and irises are cultivated. Six ponds and a pedestrian bridge connect to a waterway that runs toward Dumulmeori. It is about a 12-minute walk from Yangsu Station, and the admission ticket also covers the Lotus Museum. Construction sections are dusty and noisy, making them uncomfortable to pass through.
