Korea has several forms of martial arts, including Sunmudo, which is practiced by monks who live in the temple. Golgulsa is the only temple offering a temple stay that allows you to practice martial arts with the monks and interact with them during their daily routine.
Be sure to wear comfortable shoes; the walk uphill is a bit steep. After you have trained and watched the Sunmundo performance, you are able to hike up the side of the mountain where you will find countless Buddha statues tucked in amongst the rocks.
