The route begins at the Maso Pegorar in Andalo (path no. 301. First it climbs the slopes of Monte Dagnola, then after a short stretch it turns eastwards and runs along the great ridge of this mountain until it reaches the Sega Grande peak and comes to the Fontana Fredda area, near to which runs path no. 302 which climbs up from Sporeggio. 
Carry on to the plain around the former Malga Cavedago (1,848 m., 2½ hours from Andalo). Then turn eastwards on path 338 and head for the Cavai Valley; after the Sella del Montoz saddle you come to the Bocchetta di Val Scura pass (2,376 m.). Go down the Scura Valley, passing mountain pines on you left in the last stretch, until you meet the flat path (no. 330) which goes to the Malga Flavona. 
Continue along no. 369 to the bridge over the Rio Tresenica river and at this point turn right and follow the mule-track (path no. 314) to Lake Tóvel. Alternatively, at the end of the Scura Valley, turn right and climb up towards the Prà dell’Asen meadows as far as the Malga Termoncello and, with path no. 339, you come to Lake Tóvel.
