Marvel Cave, located on top of Roark Mountain, Missouri is a National Natural landmark. One of the most fantastic features of the cave is that they offer Lantern tour. All the lights in the cave are shut and all the members are given a lantern for lighting purpose. At this time the cave looks awesome and this is a wonderfully romantic tour. There are stunning formations in the cave include bell formation cave, throne-like cave, which makes the marvel cave even more special.
