The GTA is a fascinating trek along the mountains of Piedmont; from Colle di Tenda, the last part of the trail runs from the Alps to the sea.

The high salt route (also called Limone-Monesi or Via Marenca) is an old 63 km road along the Italian-French border. The most fascinating section is from Colla Melosa to the crossroads of Colle di Tenda, at an average altitude above 2000 meters, recently reopened to traffic with rules and toll.

Anyone who loves mountain biking and is in good physical condition can take the road from Colle di Tenda to the Vallee des Merveilles or the hinterland of Ventimiglia. You need a couple of days to get from the Alps to the sea. Limone is located along the international Turin-Nice railway line.

Three national or regional parks surround the Colle di Tenda area, providing breathtaking views, relaxing walks and interesting sites rich in history.
