Inspired by the great photos made by Fred Kruijen, I visited this location during an overnight trip to the eastern Vulkan Eiffel. It is a very nice area, with interesting geo paths explaining all aspects of the Maria Laach Vulkan area. And the minerals (Blue Hauÿn, yellow Titanite) over there are beautiful. Even Topaz can be found.
