Champ du Feu, at 1099 meters, is the highest mountain in the Bas-Rhin department of the Vosges in Alsace. It lies between the towns of Belmont and Le Hohwald and consists of an extensive high plateau with forests, meadows, and moorlands. The area is a popular nature and recreational area. In summer, it is mainly used for hiking, mountain biking, and nature observation. In winter, there is a small ski area with cross-country trails and simple slopes for winter sports. The brook La Serva originates from Champ du Feu, later forming the Cascade de la Serva. In clear weather, the summit offers wide views over the Vosges, the Rhine plain, and as far as the Black Forest. The area is particularly known for its tranquil nature, high moors, sunrises and starry skies, as well as well-marked hiking trails.

A very well-surfaced road with practically no traffic leads up from Dabo. If you want to continue to the sandpit, you have to take a well-maintained gravel road, which is easier to drive on than some paved roads. At the sandpit, you then meet a paved road again.

Saverne was already a Roman military post in the 4th century. From the 15th century until the French Revolution, Saverne was the residence of the powerful bishops of Strasbourg. The Château de Rohan, which boasts the longest neoclassical façade of any building in France, still bears witness to this.
