Hiking - Terre Rouge Lakes

From marker 90a, next to the Chalet Marano hotel, head towards the Terre Rouge lakes and take the path that rises above the chalet. Turn left to reach trail marker 91. Turn right, still heading for the Terre Rouge lakes. Cross a scree slope, then descend towards the Vallon de Terre Rouge, overlooking a peat bog. Close to the stream, a path climbs up from the right and joins the GR at a marker numbered 91. Turn left up the Vallon on the right bank; then the slope becomes gentler and you have to ford the stream. Leave the Vallon and join the path from Col Mercière at marker 92. Continue left towards the Terre Rouge lakes. After a short, winding climb, pass a first lake, then a second and finally a third, and reach marker 93. Return by the same route.
