Route B - Pas d'Enfer

Some rounded stones allow you to work on your foot placement. The steep climb of Pas d’Enfer teaches you how to handle steep slopes. Don't hesitate to walk to conserve your breath during the ascent. 2.250km of forest trail allows you to lengthen your stride. Finally, a passage taken downhill requires more attention to negotiate the uneven ground.
