The Trivio track, under the municipality of San Leonardo, is one of the most beautiful mtb tracks of The Valli del Natisone. It’s a challenging track for experts. The track is fast, divided between fluent parts and others more technicals. To find the starting point go from San Leonardo uphills following directions to Altana – Iainich and just before Trivio, on the right, there’s the track that leads you downstream. Once in this area it’s highly recommended a visit to the waterfall called Kot.
