Youth hostels are ideal places for non-formal education. Educational opportunities are an integral part of each youth hostel. Experiencing nature and the environment and enjoying community cover the programmes of the youth hostels since the last 100 years. Many programmes allow ecologically minded and socially responsible activities. New and personal experiences inspire the participants to help shape the world's future. Many of our experience programmes are mentored by educators who are experienced in the teaching of sustainability topics. By mid 2018 the existing programmes shall be assessed by the programme-checker “Education for sustainable development” of the German Youth Hostel Association.
