Goyomatsu Shonyudo Limestone Cave is a roughly 200 meter (650 feet) long cave. Illuminated by sets of colored lights, visitors can access the cave and travel with a tour group for a small fee. Deep within, you will be able to see interesting sights, like the cave's large number of stalagmites and stalactites. The largest of these pillars, "koganebashira", is a mighty 8 meters (26 feet) tall. Goyomatsu Shonyudo Limestone Cave is a great location for some guided adventuring with the family.
