Banyasa Cave Dharma Hall is a cave temple in Gayagok-myeon, Nonsan. It has a Daeungjeon hall and a cave Dharma hall built inside an abandoned limestone mine, and cold air blows through the cave even in summer. The parking lot is large, and visitors park at the entrance and walk a short distance to the temple. The entry road and the way down are narrow, so drivers need to be careful.
