No necessarily to the summit

An alternative...

I think this could work. You also have a slight play on words because "to get to the top" means "to succeed". Or in this case, it would be the top of the mountain.

This is clearly a serious notice with a “happy” (friendly) tone to it, but a serious notice, nonetheless. So I would render it in the style that serious notices are often written for English thinkers.

Like you say, it should be as short and effective as possible; to achieve this, it needs to be as explicitly clear to the English reader as possible. So I would add “Remember” at the beginning, which is intended to actually get the reader to “remember” what they’re reading (a good idea for serious notices). I would also break the sentence up (see below), to make it more effective (i.e., more “rememberable”).

Any sort of literal translation here is most likely not going to have the intended effect on the end (English) reader, which is to get them to remember the important matter of reaching the summit without accidents/incidents. That is why I would render it that bit longer in the English than in the Spanish (a rare occurrence!). It’s still a very short and effective message in my view.

Cheers.

how about this?
