3 points of interest

  • Flora

    The alpine anemone

    The alpine anemone or the alpine pulsatilla blooms here in the spring. It is a plant with a downy covering of white hairs on the large drooping flowers which are dark purple, contrasting with the bright yellow of the numerous stamens, and with very indented leaves. In summer, its fruits with a long pappus, or tuft, form a feathery seed head atop the stem. Although it is frequently found in localised areas, it is nevertheless a rare species dependent on steppe meadows in the Durance valley.

  • Flora

    The larch

    Golden yellow needles in autumn, purple cones in the spring... The larch offers colour interest throughout the year, and rather suits its title "the tree of light". It drops its soft deciduous needles in autumn and winter. In spring, the slender branches of this conifer are dotted with female flowers, which will develop into cones, and male flowers. The larch thrives on the north-facing slopes and lights up the mountainsides. 

  • Fauna

    The bullfinch

    Gentle and melancholic calls can be heard coming from trees in the forest. They are the calls of the bullfinch, a plump and timid little passerine. The male can be identified from his pinkish red underside, while the female's is beige. Both have a black cap. They often live in small groups, staying in contact with one another through their little calls. It is a year-round resident.
