Tour du Mont Blanc, Day 4: Ville des Glaciers to La Visaille

The Lex Blanche glacier pouring off the Mont Blanc massif, on the way down into Italy

Tuesday, August 4: over the Col de la Seigne and into Italy

Day 4 was the day we walked from France into Italy. One big climb up to the Col de la Seigne, a border on the top, and then a spectacular descent, with the glaciers of the Mont Blanc massif spilling down right in front of you. This is Day 4 of ten on the trail; the overview and the all-days map are in the trip summary post.

The day in numbers: 9.3 mi / 15.0 km · 2,526 ft / 770 m up · 3,031 ft / 924 m down · 6h22 on the trail, 4h11 moving · high point 8,268 ft / 2,520 m on the Col de la Seigne · Ville des Glaciers 1,838 m to La Visaille 1,683 m (watch).

Back up the valley

Buffet breakfast at Base Camp Lodge in Bourg-Saint-Maurice was a bit of a zoo, so we took ours out to the patio.

Then we mustered for the taxi back up the valley we'd come down the night before, past Les Chapieux and on to the end of the road at Ville des Glaciers. The day started at a small Beaufort cheese factory, with calves grazing outside. Windy!

A sign at the trailhead tells the story of this valley in June 1940. The Col de la Seigne was an obvious way in for Italian troops, and French ski scouts and a blockhouse held the valley against the Italian offensive until the armistice on June 25. Keep that in mind for later.

Up to the Col de la Seigne

Across the valley, the Aiguille des Glaciers was showing off its glacier in the morning light.

The whole ascent is above tree line, through high pastures dotted with ruined stone huts and fireweed.

Looking back, there were views across to the ridge we'd come down the day before.

We topped out on the Col de la Seigne, 8,268 ft / 2,520 m, at 10:50, and stepped over the border into Italy. We spent eighteen minutes on the top.

The variant, Day 4 edition

On the Italian side, under the limestone spikes of the Pyramides Calcaires, our guide took us off the main trail again, this time on a short variant past what's left of the WWII positions up here: old fence posts marching across the meadow, a ring of rocks around a pile of rusty barbed wire, and the wreck of a position still lying in the boulders.

On the way back down to the main trail, we saw our first marmots of the trip, hiding in the rocks. There's one in this picture. Squint.

Lunch by the Rifugio Elisabetta

The descent was spectacular, with the Lex Blanche glacier and its glacier-fed river right in front of us the whole way. We ate lunch on the hill next to the Rifugio Elisabetta from 12:05 to 13:16. We were supposed to spend the night here, but it was booked up. Hence the taxi rides.

The road to nowhere

Below the refuge, the trail drops into the beautiful Val Veny and onto a straight, flat, abandoned road across the valley floor. Our guide's theory is that Mussolini built it for an airport that never came to be. I haven't been able to prove or disprove it, and I like the story too much to try very hard.

Lac Combal

Near the Combal lakes, the turquoise glacial runoff mixes with clear spring water in the streams, and you can see exactly where the two meet. Add fireweed on every bank and it's a little ridiculous.

From there it's tarmac, shared with quite a few cyclists, and we mostly followed the road down to the bridge at La Visaille, where cars are allowed and our transfer van was waiting. We got there at 14:54.

Courmayeur

The van ran us down the Val Veny into Courmayeur, with a stop at a grocery on the way. Our driver was from Moldova by way of Padova. Home for the next two nights was the Hotel Triolet: private rooms with their own showers, which felt like a luxury after the dorm.

Showered up, L. and I went looking for a drink, ended up buying it at the grocery next door, and took it out to the adjoining patio to chill until dinner. Dinner was family-style pizza at La Padella, and we got a bit rained on during the walk back.

Tips for Day 4

  1. Take the short variant past the WWII remains on the Italian side of the Col de la Seigne. It adds very little climbing, it's quieter than the main trail, and that's where the marmots were.
  2. Book the Rifugio Elisabetta early if you want to sleep there. It fills up, and we didn't get in.
  3. Stop at the Lac Combal. The turquoise water and the fireweed are worth a few minutes, and after that it's road walking to La Visaille.
