Beneath the forest canopy, you can discover numerous traces of bygone times, still visible or legible; only the "barracks" have disappeared. During a guided tour with one of the site's enthusiastic volunteers, you can explore the underground tunnels and discover the organization of this impressive military infrastructure. Of course, you can also visit the surface infrastructure yourself, following the marked route, where the panels provide detailed explanations. An application, "Site du Grand Canon de Zillisheim," is also available for download.
