I disagree about river travel. In Europe, rafts were more common because of the large animals. It’s nearly impossible to cross the Seine with a horse in a canoe. But on a raft, you can do it. Entire civilizations migrated using major rivers in Europe, on rafts. And later, barges. Pretty much every major city is built on a river for a reason.

Hell, they’d cut the trees down on the river banks on either side and lash ropes to horses walking on either bank and pull things upstream that way. Huge things.
