A varied route through forest, prairie, moraine and cliffs striped with waterfalls up to 2782m to reach the Fressinières pass, which is also known as the Orcières pass.
"Whilst coming down from the Fressinières pass one July morning, where there were still névés on the the slopes that had the least sun, two animals were running in the snow. Two roe deer at 2500 metres in altitude! What fantastic adaptability! »

From the Cascades Car Park, take the path to the left, where you will find the entrance to the National Park, indicated by three explanatory panels (Leave the bridge that leads to the winter trail to the right). Cross the footbridge over the Oules stream and follow bends in the path along a large waterfall before crossing a zone of scree. As this 'summer' trail crosses an avalanche zone, it is not used in the winter. It has a gentle slope and is wide, enabling the inhabitants of Dormillouse to restock with the help of tracked wheelbarrows.
