An easy route with a well-marked path, where you can walk freely around the magnificent lakes. The route begins at the Saint Guérin dam (at 1580m) which must be crossed, then a path climbs to the Col de la Louze (at 2119m above sea level) and continues on the right. You then have to cross a scree marked by large cairns and traces of white paint to a small pass from which you can see the first lake.
