You can try natural=desert and desert=salt as salt lakes are really deserts made of salt instead of sand or rocks.

The Uyuni Salt Lake in Bolivia is tagged like this. See: http://www.openstreetmap.org/#map=9/-19.9462/-67.2281

But that doesn't seem to be rendered on osm.org . I know, don't tag for the render - but it seems strange to tag a salt flat which inundates every year as a desert...

Under wetland you can find wetland=saltern and wetland=saltmarsh - if that fits...

Note:

  • The Great Salt Lake is tagged as natural=water...
  • If you tag salt lakes as wetland they are not rendered in zoomlevels greater than 11...

A salt lake is not necessarily a desert. It is more the prephase of a dry lake which could probably be classified as a desert. Therefore, I would rather use something like natural=water water=salt_lake. But I am not really an expert in this.

That looks fine for "a salty lake". But in the mentioned Uyuni Salt Flat for example, most of the time it's a salt desert. Then the rains come and it turns into a very shallow lake for a few months of the year.

@joost In that case it's a salt pan and not a salt lake, isn't it? For salt pans natural=desert + desert=salt should be used, see Gnonthgol's answer.

should this question be edited if it's not really asking about salt lakes?
