(S/E) The hike starts from the hamlet of Narreyroux (there is a car park at the start of the hike).
Follow the Combe stream for most of the trail, which will always be on your right. You will soon reach a car park.
(1) Continue opposite, still on the right bank of the stream, until you reach a crossroads.
(2) At the cairn, after leaving the woods, on a "flat" area, leave the trail that leads to Lac des Neyzets and Pointe des Neyzets and turn left onto the trail, which is not very visible at first (the direction of the pass is engraved on a stone in the cairn). After a steep climb, you will reach Col du Bal.
(3) The return journey is via the same route (S/E).
