This trail is accessed from the eastern side via Monte Cornizzolo. It begins at the Sasso Malascarpa (Malascarpa Saddle), where there is a great cliffside overlook of Lecco and Lago di Garlate (lake).
Initially, the singletrack is very technical as it winds its way among some boulders right along the knife-edge like ridgeline. Then you'll head steeply downhill through a dense forest to a gap and a trail junction known as la Colma, where the main difficulty is the overall steepness of the trail. If you're following the Sasso Malascarpa e Lago Segrino (Malascarpa Saddle and Segrino Lake) loop, turn left at this intersection onto la Colma to Rifugio Terz'Alpe.
