I was inspired by the question "What should one do when climbing if someone above you yells ROCK?" to ask what the equivalents are around the world.

So, what would I shout to warn someone below me of falling rocks?

Equivalently, what word should I react to when I hear it shouted?

I've created an answer as a Community Wiki to accumulate knowledge from everyone; please contribute to that.

    This question in general is interesting for climbers but it's not really fitting in the scope of Stackexchange. Questions which generate list-type answers aren't prefered here. Similar is this one which was closed too. I am sorry but I vote to close therefore.

    I think this is a very useful question. Lets protect it and make one community answer and everyone contributes there.

    This is the kind of question whose answer could be very helpful. The alternative is to have dozens of more specific questions - would that be a better resource? I've made my answer a CW as that is better than one answer per region and can be curated for consistency, but I'm open to suggestions that would improve this and make it a valuable contribution to The Great Outdoors.

    Really, @Guran? Do you manage them all before the rock lands?! Commented Apr 7, 2017 at 11:25

1 Answer 1


North America

English Canada / United States

"ROCK!" (pronounced /rɒk/)

French Canada

"ROCHE!" (pronounced /ʁɔʃ/)


European Alps

"CAILLOU !" (pronounced /ka.ju/)

It's French but also sometimes used by non-francophone climbers and hikers in the Alps. This word is used to warn when a hiker (or a goat!) up the trail loosens a rock that crosses the trail lower down. Fun fact: Literally it means pebble.

"STEIN!" (pronounced /ʃtaɪn/)

Used in German speaking regions. Exact pronunciation varies in between regions due to dialects, but should be recognisably similar.

Great Britain

"BELOW!" (pronounced /bɪˈləʊ/)

Used in climbing and in caving; amongst others (e.g. scramblers), knowledge of it is variable.


"STEN!" (pronounced /ste:n/)

Mainly used in climbing and caving.



"Loose rock!"


"Watch out!"
