Trying to create a really specific path up on a hill in the terrain

Hi everyone,

I’m trying to craft a really tight path up a hill in my terrain and I’m not having a lot of luck.

Context

I’m creating a first person shooter that takes place in a large outdoor environment. The goal of this particular stage is to ascend a large hill going up a very specific path.

I’m sort of new to Unity and not having a lot of luck crafting this particular aspect of my environment. Is this something that can easily be done within Unity’s terrain builder or should I seek out the assistance of an external program?

Thanks in advance for your assistance.

it can be done in unity
