Beginner question: How to capture the sense of scale?

Hi everyone,

I am an amateur/beginner in the field of photography but I have thoroughly enjoyed taking pictures of everything throughout my life. Recently, I went on a trip to Norway to see the fjords, and I was honestly awestruck by the magnificience of this place (probably the most beautiful place I have ever been in). The massive cliffs plumetting straight down into the water, our ferry being absolutely dwarfed by the mountains surrounding, etc.

So naturally, I tried to capture this in pictures. But, to my surprise, none of the pictures did justice to the sense of scale that the fjords give you in real life. It all looked "flat", or "small".

And it's something I had already sort of experienced in NYC, but to a much lesser extent, so it didn't "bug" me as much as with Norway.

So I was wondering what technique or equipment do you guys use to preserve the sense of scale in your pictures, especially when faced with these sorts of "dwarfing" sizes (NY skyscrapers, mountains, cathedrals, etc.)?

Thanks in advance for the replies.
