Nice route through the protected site of the Nant Valley. Steady climb mainly through the forest and arrival at the famous "hole". The passage is done without a backpack, which you will push in front of you, for the duration of the passage. Claustrophobic ok! Not suitable for dogs I would say. A few dizzying passages just before the arrival, caution and concentration and all is well! Descent and return to Pont de Nant or Les Plans sur Bex, quite steep descent towards the end.

If you are looking for a unique and captivating hike in the Vaudois Alps, you can visit Trou à l'Ours. This rocky site leads you to a narrow chimney in the rock face, where you must ascend or descend using a chain. The passage is not for the faint-hearted, but it offers thrills and a breathtaking view of the Vallon de Nant.
