Come with us to the Jungferweiher! It is the oldest maar in the Vulkaneifel with a special flora and fauna - a habitat for endangered species - and today also an important bird paradise. Be impressed by the Ulmen maar gallery, which connects the Jungferweiher pond with the Ulmen maar. Our maars are as individual as we are, each with its own story. Experience and learn more about the eventful history along the way, water our elixir of life, a vivid detour into the history of the earth/volcanism in the maar gallery and a view of Ulmen maar and castle at the halfway point.
