Several European long-distance hiking trails lead through Éislek. These long-distance hiking trails connect regions and countries over hundreds, sometimes even thousands of kilometres. Due to its location in the heart of Europe, Éislek is situated along several important European hiking highlights. The trails can be walked in both directions and are marked with supra-regional markings. Such trails are particularly suitable for adventure-seekers who like to plan their tour over several days or even weeks.
European long-distance hiking trail E2: The E2 runs for more than 5,000 kilometres from Scotland to the Mediterranean. The trail starts in Luxembourg at the border triangle in the north of the country, on the River Our. It follows this river for many kilometres to the south. It leaves Éislek south of Vianden to meander through Mullerthal and the Moselle region, where it finally reaches Schengen and the French border.
European long-distance hiking trail E3: Covering almost 9,000 kilometres, the E3 leads from Spain to Bulgaria, from the Atlantic coast to the Black Sea. In Éislek, the trail first passes the Upper Sûre lake and Esch-sur-Sûre. It then crosses the region via Wiltz, Clervaux and Vianden before turning southwards.
GR15: The GR15 leads from Arlon in the south of Belgium to Monschau in the west of Germany. Between Arlon and Bastogne, it repeatedly crosses the Luxembourg border to head north along small, less frequented paths. This play with the border can symbolise the European idea, as this long-distance hiking trail leads through a total of three countries.
GR57: The GR57 connects the Belgian and Luxembourgish Ardennes, known as Éislek. From Liège, the trail leads either to Libramont, where the western Ourthe has its source, or to Ourthe near Gouvy, where the source of the eastern Ourthe is located. From there, it enters Luxembourg to reach Diekirch via Troisvierges. The Luxembourg sections offer scenic highlights and mostly run along the Escapardenne Lee and Éislek Trail
