No, I mean adding verts and splitting up your terrain squares and draw the path into it, this will allow you to set the path as a seperate surface, then just apply a path texture to it.
Or... You might just be able to move your verts around to make the path all bendy, you don't have to have a perfect grid for a terrain after all.
