Luyang Cave is loacated at San Andress, it was the cave that the natives used as a refuge from the attacking Moro Pirates during the 17th century. The pirates uprooted several sili (red peppers) and some dried leaves at the entrance of the cave to suffocate the natives inside. At the present a mini-groto was built in memory of the massacred natives to appease their souls. Today it also attracts visitors because of the cool damp air that can be felt while going deeper into the cave.
