In such a densely populated and developed little country, it seems impossible to escape civilization. But there is one beautiful corner of Belgium where you can be truly alone—the Hautes Fagnes Natural Reserve, in Belgium's Eastern Cantons.
The Hautes Fagnes (or Hohes Venn in Dutch) is Belgium's largest nature reserve and part of the 700km2 Hohes Venn-Eifel park, which spans the Belgian-German border.
The park includes 10,000-year-old alpine sphagnum bogs, waterfalls, and hundreds of kilometers of hiking trails. While some of the trails are paved and easily accessible, others see you clambering over tree roots, climbing slopes, and wading through streams. You can feel a million miles from the nearest human being, all within easy reach of civilization.
