Located at the entrance of Sanjeonghosu Lake, Pyunggang Botanical Garden opened in May 2006, and was designated as a habitat for preservation by the Ministry of Environment in 2009. The garden has on exhibit both native plants and species of plants from around the globe. Additionally, the garden features an exquisite collection of over 1,000 different alpine plants that normally reside on an altitude of 2,500 meters.

The scope of the garden is comprehensive, but it is divided into 12 themed areas, including a Rock Garden, where the largest alpine plants in Asia are concentrated; a Wetland Center, which mimics the natural ecology of a wetland region; a Pond Garden consisting of roughly 50 ponds lined with gorgeous flowers; a Moss Center where moss that grows in deep valleys and forests can be seen; and a Grass Square, which serves as a green common year round. The Pyunggang Botanical Garden, serves an important role in preserving rare plants, but is also creating a new botanical garden culture, and serving as a center for public ecological education.
