Namsan Outdoor Botanical Garden is a specialized green space located at the southern base of Namsan Mountain, functioning as an educational botanical exhibit rather than a traditional ornamental park. The facility is divided into various themed sections including a native plant garden, a wildflower garden, and a wetlands area that showcase the biodiversity of the Korean peninsula. Unlike the main Namsan Park trails, this area focuses on the conservation and display of specific botanical species. It features gravel and paved paths that wind through dense foliage, providing a structured look at regional flora. The garden serves as an important ecological buffer zone connecting the urban landscape of Yongsan to the forested slopes of the mountain.
