I can't get to a place with a question mark in the prologue (The Witcher 3: Wild Hunt)
Spoiler
There is a hill, and there are ruins on it. Po ran around this hill and did not find how to get up there.
I met one side quest related to the main storyline, it is quite possible that you will get there according to the plot.
Well, or look for caves nearby, maybe there is a passage ...
There is a wall that has fallen and leaned against the slope. You can climb it. There's a bandit camp there, I think.
yes, run around there, I also couldn’t for a long time then climbed from the south side somehow
You need to go to the path that goes a little west of this question, and from there turn off as soon as you find yourself opposite the hill with the ruins.

KelevRa6381 correctly said that there is a fallen wall there. You can climb up on it. There is a bandit camp and in the ruined tower you can find a drawing of a silver / steel sword of the Serpent school.
