This international event devoted to nature documentaries began life in Sondrio in 1987. The festival picks the best global productions on a scientific and cinematographic level made by directors from all over the world. The documentaries feature nature reserves and protected areas all over the planet and the main objectives of the event are environmental education, safeguarding nature and the eco-sustainable promotion of the world’s natural heritage. There are also a number of conferences, exhibitions, performances and meetings with special guests, including some especially developed for schools. The screenings are free and are repeated a number of times. The event takes place in Piazza Garibaldi and the renovated Teatro Sociale di Sondrio.
