At the exit of the passage and from the moment you reach the mountain pastures, the peak to climb is on the left. In summer, the mountain pastures could be occupied by sheep. Please respect the flock and bypass it if you can. Protecting dogs may come to you. Stay calm and avoid aggressive behaviour.
    (3) For the way back, come back on yourself.
