We drove, via Eurotunnel. That probably involves the least human contact. For fans of CO2 accounting, it was about three tanks of diesel, about 240 litres or a little less. For Covid reasons, Eurotunnel doesn't let you out of your car on the trip, and for bonus points someone wanders around during the transit cleaning the sides of the carriage that you can't touch cos you can't get out... Before you go, Eurotunnel solemnly tells you on the website that you need to fill out a form for the French govt solemnly swearing that you haven't got Covid, and so on. We solemnly did this, and it was a total waste of time, as absolutely no-one looked at them.
The French mountain huts website told us to fill out a similar form, and it too was a total waste of time. Somewhat more annoyingly, the sites told us that due to Covid there would be no blankets and we needed to bring up our own sleeping bag. That turned out to be nonsense too but cos us 1 kg each. As it happened, it was a fairly warm period, and I just slept in my sheet liner anyway.
Within the refuges, the sense was of having rules, but not really caring about them. Here are the Glacier Blanc's. They carefully have a "circulation system" that makes no sense at all, because there is only one staircase, and only one entrance. People tended to wear a mask when they first went in, realise no-one else was, and then stop. They did make some attempt to enforce "only 10 people in the lobby" but although it is a fairly expansive boot-room, you can barely fit more than 10 even if you try.
In practice, we were outdoors by ourselves almost all day most days; or in the valley in our own apartment (which I chose slightly at random but was better for lack of human contact than a hotel). In the evening the huts did group meals as usual and as usual made no attempt to use all of the tables.
Supermarkets tended to have hand-san. Restaurants, supermarkets, cathedrals, buildings in general were mask-obligatoire indoors, and everyone did that. Since it was mostly rather warm, eating outdoors was hardly a restriction. On the drive back it was so hot in Dijon that it would have been quite nice to go inside into the air-conned restos, but we decided not to. Here's a pic of Vallouise's weekly outdoor market.
We may have got out just in time. The papers tell me that the govt is considering adding France to the quarantine list; not that it is clear that the UK quarantine means anything. But, we can all sleep better knowing that "Matt Hancock [is] closely monitoring [the] situation". Update: it's happened.
I think that's it. I leave you with a pic: walking up to Les Bans.
