5 points of interest
- Water
Combefroide Waterfall
At the beginning of the path, is a big waterfall that you can approach on a narrow footpath just before climbing the coast. Situated on Combefroide torrent at a rocky escarpment, this waterfall has several projections and presents a total drop of several dozen metres.
- Flora
Heather fields
Over a change in altitude of a hundred metres there is a covering of heather which provides pollen for the bees and purple colour in Autumn, A small persistent shrub with tiny leaves and little pink flowers, it is called Common Heather or False Heather.
- Geology and geography
Bourelle Gorge
Since the end of the ice age, water has carved the rock and the passage of materials has created a small gorge polishing the base rock (gneiss, micaschists). The National Park has taken on the challenge of building a wooden walkway for walkers to cross this gorge.
- Vernacular heritage
Jas crossing of the Bourelle
Just above the signpost, there are the ruins of a pasture shelter commonly called the, « jas ». Often built using dry stones, this kind of shelter was used to protect the flocks during the summer season.
- Hut
Olan Refuge
Situated at an altitude of 2350 m, this large building constructed in 1957 was carried away by an avalanche two years later. A witness to this is a concrete slab below the refuge. Rebuilt in 1966, it was definitively extended in 1978 with a capacity of 54 places. A stage of the Tour de l'Oisans (GR 54), it welcomes hikers in the summer season and provides a shelter in the winter; it belongs to the Club Alpin Français.
Description
- Stay on the road and cross a mountain stream.
- Immediately on the left, a path leads upwards following the banks of this stream. Take this path and start the ascent with some winding sections among the screes and go on to cross a heather moor. The view gradually opens up onto the Navette valley and the hamlet of Les Portes which lies opposite.
- Cross a stream and then, a few dozen metres further on, at an intersection take the upward-winding path on the right. You reach the montane zone among alpine grasslands, offering a view over the village of La Chapelle and the Refuge de l'Olan. Nearby, an old concrete slab testifies to the passage of an avalanche in the 1950s.
