The exposure grade describes the potential consequences of falling or slipping off the path.
Low Exposure: The path is on completely flat land and potential injury is limited to falling over.
Medium Exposure: The trail contains some obstacles such as outcroppings and rock which could cause injury.
High Exposure: Some trail sections have exposed ledges or steep ascents/descents where falling could cause serious injury.
Extreme Exposure: Some trail sections are extremely exposed where falling will almost certainly result in serious injury or death.
This route takes you on a loop from the center of Les Houches to the Tête Rousse Hut, giving you the chance to see climbers up close on their Mont Blanc attempt. Going up, you will take the "Chemin des Rognes," a recently rehabilitated trail that provides a quieter (but more technical) alternative to the classic Nid d'Aigle route.
Enjoy the calm and the amazing view of the Chamonix Valley, because once you reach the Baraque des Rognes at 2800m, expect bigger crowds.
At Tête Rousse, watch as climbers tackle the infamous Couloir du Goûter and enjoy the view of the surrounding peaks and glaciers.
Keep following the trail on the way to Bellevue When you're ready for the climb down, retrace your steps before taking the trail down to the Nid d'Aigle hut, where you'll have the opportunity to get closer to the Bionnassay Glacier.
From there, just after a steep bit with some ladders, the trail becomes easier until Bellevue, where the final descent towards Les Houches starts.
A number of alternative routes are available; here you'll follow the old route used by the TDS trail race.
