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.

🌄 Stromberg – Limestone cliffs near Niederkontz A dry rock formation on the Stromberg summit – 314m high – surrounded by forest, with views of the Moselle Valley and the Luxembourg hills. A tranquil spot with an impressive panorama. Tip: Ideal on clear days – a short detour from the path is worthwhile for a nature photo with a truly striking effect.

📍 Mondorf-les-Bains Center Finally (or as a prelude), the trail leads through the expansive Parc Thermal – with shady avenues, manicured flowerbeds, babbling fountains, and elegant spa architecture. A place that combines exercise and relaxation, ideal for taking a breather or lingering. 💡 Tip: Be sure to slow down a bit – the park invites you to see, feel, and enjoy. If you like, sit on a bench and watch the day pass by.

📍 On the edge of Altwies, slightly elevated Slightly off the path, nestled beneath rocks, stands a statue of the Virgin Mary – surrounded by a small bench, flowers, and a tranquil atmosphere. Not an official pilgrimage site, but a place to pause. The rocks provide shelter, and the bench invites you to silence. 💡 Tip: Sit down, breathe deeply, and take in the surroundings. 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.
