There's nothing that makes a joke funnier than someone who explains why that joke is statistically unsound.

At your service, with delight!

The actual funny part of it is that campsites in France are actually starred just like Michelin restaurants on their maps (and on their signs - France of course loves to over-sign everything). A 3 star municipal campsite could be 40 Euros for the night!

One of the reasons I spent so many nights in apple orchards.

There you go. That's why if I choose to go on a long distance hike it will be in the US rather than France.

Here's one 6km away from camping

Here's one 3km away,

< 3km,

2.3km

I'm sure we can find one closer, but <10km seems to be not out of the ordinary.

France is 643,801km^2 (that number may include some departments not physically part of "Metropolitan France"). If they were uniformly distributed, 632 restaurants would be 1 per 1018km^2. A land area of 1018km^2 is actually a box about 32km per side, and so on average, a restaurant and a campground would be about 16km apart.

So ... you're not far off.

IFFFFF the restaurants were evenly distributed. They almost certainly are not.

I would think municipal (the kind you find in a town) campsites - the kind you find in a town would be closer to a Michelin starred-restaurant - also usually in a town, then on average when just looking at total area.

Anyways, it's fun to look up things on the Internet I guess, but maybe go and camp in France, and go have some dinner out every once in a while - a little meatspace joie de vivre certainly won't hurt. Usually.
