Brother.
I don't know why you are in Varazze, land of the razor crimp, of the snappy hold and of the nonsense eliminates.
Anyway, Rampage is notoriously hard to find even with the guidebook and features a long walk.
I wouldn't venture there without a guide.
Also, I think it's on a small terrace, which maybe isn't exactly suitable for children.
In any case, I'll try to find some info.
