Castalia

Most remembered for the former Blue Hole attraction, this rural village is known for its mysterious “blue holes” - seemingly bottomless ponds filled with spring-fed water that lacks oxygen. Visit the Castalia State Fish Hatchery for an up-close view of one of these “blue holes” and discover coldwater trout streams and a picturesque landscape, or hike Castalia Quarry MetroPark where you can see the islands from the elevated viewing deck.
