Cherney Maribel Caves County Park occupies 75 acres on the West Twin River north of the Village of Maribel in the Town of Cooperstown. A rugged cliff line, generally paralleling the river, separates the gently rolling, partially wooded upland area from the wooded lowland adjacent to the river. The foot of the cliff line contains small caves and openings in the rock layers. Tours given on the third Sunday of each month May-Oct.
