Every place in France, filed by how alone you will be when you get there.

“The view over the roofs is free, and it does not require the funicular, the queue, or the man who wants to tie string round your wrist.”

This is the top of the axis: the most contested square metres in the country. Scroll and the ground darkens as France empties out — down to a departmental road on the Causse Méjean, where there is no attraction at all and that is the entry.

The Axis

23 guides · 10 down to 0

There is no region menu. Every guide on this site is filed by one number: how alone you will be when you get there. Ten is a queue. Zero is fuel and a spare plan. Set the range you can tolerate and the site rearranges itself around it.
