The Col du Petit St Bernard (or “Little St Bernard Pass”) is an accessible climb by Alpine standards. It may be 30 km with 1,400 metres of climbing, yet the gradients average less than 5%.

It’s not a quiet idyll (the border with Italy is at the summit and it’s an important transport route), but the scenery after La Rosière is stunning and there’s lots of history too (see below). The steady gradient makes it a good opportunity for finding your rhythm while climbing for a decent length of time.

Tip: there are quite a few little roads around the main climb which allows you to incorporate quieter stretches, but they’ll add gradient too. This route sticks to the standard climb, but play around with it if you want to make it quieter and/or tougher.

You spend more than two thirds of the ride climbing the wooded Isère valley above Bourg Saint Maurice. 

Suddenly, after leaving La Rosière, you round a 90° bend and are in another world. You leave the woods, trees, houses and businesses behind you.  The road winds up the side of a softly green U shaped valley with pastures stretching up to grey peaks.

The final eight kilometres stretch ahead of you and, on the horizon, you spot the Hospice du Petit Saint Bernard. It’s stunning.

1. Bourg Saint Maurice to La Rosière: 0-23 km

It’s a short spin to the start of the climb. After Seez you head up an impressive series of hairpins. Slowly but steadily you climb: kilometre markers never announce gradients that are too alarming (4-6%). You’re generally within forest, passing houses and the odd little village.

The best views come when you get to La Rosière, a small ski station at about 1850m.

2. La Rosière to summit: 23-31 km

From La Rosière it’s 8km of blissful views down the mellow valley with the Torrent du Reclus below you. Gradients average a manageable 4.4% which makes the whole thing rather enjoyable.

A couple of kilometres after you leave La Rosière, you round a corner and, up ahead, you can just about see the statue of Saint Bernard. It’s not far from there to the Hospice St Bernard and the Petit St Bernard pass.

A fun descent back to La Rosière

3. Descent to Bourg Saint Maurice: 31-62km

Enjoy this swooping descent - just watch out for traffic.

There are plenty of options for diverting off the main road onto smaller, narrower (and steeper) descents.


Stock up in Bourg Saint Maurice before you leave as there’s not much before you hit La Rosière. Bourg Saint Maurice has plenty of supermarkets, bakeries, cafés and restaurants.  

Other options:

  • circle
    23km: La Rosière is also a good place for a rest and refreshments should you need it.
  • circle
    31km: There’s a small café at the top of the col and the Hospice du Saint Bernard, one kilometre beneath the summit, also has a restaurant.


We stayed at The Peak, in the ski station of Sainte Foy Tarentaise, about 20km from Bourg Saint Maurice. It’s a nice village, and we very much enjoyed our stay. Riding the Col du Petit Saint Bernard from Sainte Foy is quite a treat because you can add some fun miles and meet the main road on its way to La Rosière.
