This point-point, open-course route takes you from the easternmost point of Joshua Tree National Park to its westernmost point, along the park’s longest “axis”. It is about 80 miles long. The GPX route shown below is the one Sam Kottoor followed, but it is not required to go this route, and you are encouraged to make your own, as only the start and end points matter. A link to his trip report is found below. It is acceptable to attempt either from East to West, or from West to East.

Tour de la Lauziere par le GRP (suivre balisage)

Départ/arrivée : col de la Madeleine

Boucle magnifique mais très peu de points d’eau et de ravitaillement (route uniquement au logis des fées) 

Ce tour favorise l’autonomie et la gestion 

Attention aux patous en saison
