If you don't just love asphalt and if you also like to drive on non-asphalted paths, you can only suggest going around the reservoir (approx. 10km). Again and again there are beautiful views of the lake.

The water from the lake is used to wash the stones in the nearby Hönnetal limestone works. The washed-out sediments are washed back into the lake and settle there. The lake in the quarry owes its name to the intense color of the water: The Blue Lagoon. It is 80 meters deep and has a water temperature of 8 degrees.

Easy parking, nice interesting path with a good view of the limestone quarry. The observation tower is also worthwhile. Here you can see more than 40 km in good visibility. A board on the strand helps for orientation.

There is a wonderful trail, from the dam wall down to the Volmestrasse. Coming from the street over the wall and then left down. Mixed but solid ground. Roots and some stony passages are also on the way. Also suitable for beginners, but with an eye on 👀 pedestrians can come uphill too ... enjoy the wonderful descent through untouched nature 🏞⛰ in the local recreation area Glörtalsperre

The popular local recreation area around the picturesque Hexenteich invites you to take relaxing walks and adventurous hikes. In an idyllic atmosphere you can unwind and enjoy nature. Those who are particularly attentive on their tour around the pond will not only discover the tall wooden sculptures, the romantic hearts, but with a little luck even red-eared turtles.
