The day before our trip to Chamonix we went to the Tourist Office of Bourg St. Maurice to get a map, since our visit to Cormet de Roselend we knew that there was no need to go down to Albertville to reach our destination, but the route of the great Alps is the same. We studied the plan at night I concluded that passing the Col du Yoly would have the same or better views, so in the morning we operated without GPS and I was sent by the most comfortable route through Albertville. Passing Cormet we turned the GPS on and there and I recognized the route we wanted . Once down in the harbor and after passing Hauteluce the GPS insistently told me to turn to the left. My stubbornness led me to ignore it and go to the Col du Joly, it became so heavy that I had to turn it off. Finally, after a quite relaxed climb we found a truly awesome spectacle. We were at 1989 meters altitude and before us the genuine and unique Mont-Blanc but the road did not continue, two forest tracks started from this point and were totally inadequate for tourism. This leads me to conclude that we must heed the GPS, despite my stubbornness, as it showed us one of the most splendid views of the Alps.
