Charles Town Cave — also formerly known as Crystal Lake Cave and Lakeland Cave — is located in the center of Charles Town, West Virginia, United States. One entrance was in the cellar of a bakery (since demolished) and led down to a passage about 175 feet long to a large pool of clear water about 25 feet in diameter. Much of the cave is under the current Old Opera House building. The cave is closed to the public. Rumors persist about other entrances to the cave in various Charles Town and Ranson buildings.
