Known as the ‘Village des Musées’, Treignes boasts the highest concentration of museums per inhabitant in the world – with a population of around 600, there are five. This pretty village lies in Namur province in the south of Belgium, a stone’s throw from the French border in the stunning Ardenne region of Viroinval. There is something for everyone, including 300 kilometres of walking trails, endless mountain biking options, beautiful valleys and woodlands, lazy boat trips on the river and cosy restaurants.
