About

This site answers one question: what is currently shut, restricted or officially flagged as dangerous in the Mont Blanc massif.

It is a directory of published notices, not a safety service. It reports what lift operators, mairies, hut federations and booking systems have actually said, links every claim back to whoever said it, and never makes a claim of its own. It does not know whether a route is safe, and it will not tell you whether to go. A status here can be out of date — every row shows when it was published and when we last confirmed it, and where we have nothing it says so rather than staying quiet.

If you are here from your server logs

You have seen a request from massif/0.1 (+https://montblancmassif.org/about; steven@innes.io) and want to know what it is. It is this site, collecting whatever you publish about lifts, huts and mountain routes so that people can find it in one place, with a link back to you.

If you would rather we did not, email steven@innes.io and we will stop, or add a Disallow for us in your robots.txt and we will stop by ourselves on the next run. You do not need to justify it and we will not ask you to.

Where the information comes from

Checked 7 September 2026. Sources are weighted: a mairie’s decree outranks an operator’s page, which outranks a booking calendar, which outranks a community report. Where two disagree, the more authoritative one is shown and the other is still listed on the feature’s own page.

Two dates, not one

Every status carries when the source published it and when we last checked it still stood. They are different facts and conflating them hides the one that matters: a decree from three months ago that we confirmed an hour ago is current, and a lift status from this morning that we have not re-read since is not. Rows aged past what their kind of notice holds for are marked OLD; rows we are overdue to re-read are marked OVERDUE.

Something wrong?

A wrong status is worth telling us about, and so is a hut or lift we are missing, or an attribution we have got wrong. Report it here — it takes a couple of clicks and goes to a public issue tracker, or to email if you would rather.

Who runs it

One person, as a personal project, with no commercial interest in any lift, hut or guiding company. The code is public at github.com/Deltaspace2/massif — including every source it reads and the rules it applies to them, so anything on this page can be checked rather than taken on trust.
