To get to the start, follow the D120 from Virieu-le-Petit towards Les Granges du Colombier. Park your car at the hairpin bend. See alternative car parks in “Practical Information”
(S/E) Take the path heading south, away from the hairpin bend. Walk downhill for 1 km.
(1) At the signpost indicating the direction of Chanduraz, follow the yellow markings; the path leaves the forest and heads into the meadows.
(2) At the junction of several paths (signpost), turn round to see the summit of the Grand Colombier (high-voltage pylon almost at the top). Continue in the same direction until you reach the Chanduraz promontory overlooking Lake Bourget.
(3) Take in the view and retrace your steps back to the signpost.
(2) Take the path that climbs diagonally (north-east) up the grassy slope and then, at the top, descends down the other side towards the Grand Colombier road (D120).
(4) Walk up this road, taking care of cyclists going uphill (slowly – do not get in their way) and downhill (quickly).
(5) At the signpost for La Pierre Amont, leave the road and take the path climbing to the left; it starts off gently but becomes a little trickier as it follows the ridge over fairly rocky ground, up to the high-voltage pylon. Then follow the path to the summit of Grand Colombier.
(6) Continue straight on to the pass below. At the pass, head down the road to the left (take care, watch out for cyclists!).
(7) Just before the hairpin bend, take a path on the left that descends the slope. At the bottom, head across country to Les Granges du Colombier (several buildings). Climb up behind the restaurant (closed in 2022), admire the view and head back down. Then continue down the pass road, turning right. Follow it to the car park (S/E).
