What map are you playing on?
In general, you have three turns in a space. For climbing, you have the same three turns. Fail to climb, and you move on and can't return unless otherwise stated.
Pointe Du Hoc. You can climb from 2 black sectors there. How long can you stay there? Note that the sentence "You have three turns to succeed" is in the specific rules of this scenario, strange thing when you can climb from two black sectors.
Anyway, it's so easy to win even staying only one turn in those black sectors.
