エンゲンのおすすめMTBライド

エ​​ンゲン近郊の古い火山円錐は非常に印象的で、遠くまで見渡せます。

ヘーヴェネック・クレーターは、シュヴァーベン・ジュラ山脈に典型的なドリーネ（陥没穴）ではなく、本物の火口です。地質学的には、ヘガウ火山地帯に属します。玄武岩の採掘により、クレーターの現在の外観がさらに形成されました。ここからは素晴らしい景色を眺めることができます。

Great barbecue hut, the ideal place for a break.

Strictly speaking, it's more of a path than a trail, except for one very short section. So it's not a problem, although there are currently quite a few fallen trees lying around.

The Aachquelle is the largest spring in Germany.

A very good viewpoint overlooking the crater lake, with a small rest area and information panel. Even though there is a large fence around the crater rim for safety reasons, a good view is still possible.

Beautiful viewpoint from the hiking trail around the crater lake of the deep blue lake and the volcanic caldera.

Follow the sign "Danube Sinkhole." Either the water is there, or it's gone. Then you've arrived at the natural phenomenon of the Danube Sinkhole. The limestone rock layers from the Jurassic period, which form a large part of the Swabian Alb, are to blame for the disappearance of the Danube. Chemical dissolution processes create cracks and cavities within the limestone, into which the Danube water seeps. In summer, the riverbed dries out completely. However, the Danube hasn't completely disappeared – completely in summer and partially in the winter months. Exactly 183 meters lower and about 12 kilometers away, it then reappears: in the Aachtopf, Germany's largest spring. The water takes about 60 hours to complete its journey. The Danube's journey is far from over. Via the small river Aach, the water flows into Lake Constance and then via the Rhine into the North Sea. And the rest of the Danube? It flows through a total of 10 countries to the Black Sea.
