The article weighs up the didactic proposal carried out by the authors in the Biosphere Reserve of the Ancares Leoneses (RBALE) with students enrolled in the Practical and Applied Geomorphology class of the fourth year of the Undergraduate Degree in Geography and Land-use Planning of the University of Valladolid. Its development has served, firstly, as a basis and a tool for geographical work in a mountain site of heritage value, a key objective of the matter. At the same time, it has allowed students to take part in a real servicelearning experience, interacting with local parties and management entities of the RBALE. This experience was awarded the “Prize for Educational Innovation by the Social Council of the University of Valladolid -2013-”.
