I wonder, is jugar montaña a set phrase or idiom representing something else?

I guess in English would be the same, ain't it?

Literally, playing mountain?? It must mean something else

I think it means to go by the way of the mountain.

Correct. Given the context in which is happening, it is just like that. :)

It isn't correct way to say it in either language, but the context tells you what's going on.

Happy campers! ;)

@Glen: That's definitely not an idiom and quotation marks underline the fact that it is not a usual sentence. However, I don't think it means anything else than taking the side of the mountain to escape. (Found the context, and to me, the author is using this expression to avoid the whole explicit sentence saying that they're feeling trapped and needing desperately to find a way out.)
