Easily navigable paths lead through the Vallée de la Bonne. After crossing the Désert-en-Valjouffrey, whose barns underline the ongoing rural activity, you will discover the U-shaped valley, overlooked by the Aiguille des Marnes (3 0460m). Once you have left the park the landscape becomes palpably wilder. The path goes by a mass of fallen rocks before arriving at the Cascade de la Pisse. Continue towards the impressive Font-Turbat cirque for a more rocky landscape lying in the shadow of the Pic d'Olan (3 564 m).
