In the Cottian Alps, between the Susa and Varaita valleys, were several variants of the GTA. An eastern route, snow-free by early June, is neglected; the main, western route is well-maintained. The GTA runs south from the Susa Valley, crossing the Chisone, Germanasca, and Pellice Valleys. The Monte Viso bypass uses two huts belonging to the Club Alpino Italiano. The trail then crosses the Varaita, Maira, Grana, Stura di Demonte, Gesso, and Vermenagna Valleys. Near Monte Argentera, in the Maritime Alps, are several more Club Alpino Italiano huts. The GTA then enters the Ligurian Alps, ending at Viozene in Ormea. Trail extensions continue to the train stations at Ormea or Gerassio, cross to the Alta Via dei Monti Liguri or lead to the Mediterranean Sea (which can be reached in about three days from Ormea).
