Boryeong Mugunghwa Arboretum is built around mugunghwa, Korea's national flower, with planted collections, walking paths, and displays of local tree resources. It gives inland Boryeong a quieter nature stop away from the beach.
The arboretum works best as part of a loop with Seongjusa Temple Site and the Boryeong Coal Museum. Come for a gentle walk and seasonal planting rather than a formal botanical-garden spectacle.
