A tranquil limestone cave on the summit of the Stromberg near Niederkontz – formed by shell limestone and a former quarry, with delicate stalactite structures. A fascinating, natural cavern space off the beaten track. Tip: Bring a flashlight – and stay under the rock roof to truly experience the soft light and tranquility within.

Whether you're religious or not – this place radiates peace, gratitude, and respect.

A great way to cruise with relatively little traffic. The view is fantastic when the weather is good: on one side you have a wide view of France, on the other side you have the Saar valley. Apart from a short section, the road is well paved.
