I've jumped off the top bridge and floated down the river from there, but I can't get through the waterfall. I've tried actively swimming down, letting the current carry me, and even swimming backwards like I needed to on the river below, but I've had no luck. But regardless of what method I've tried so far, I can't get through the wall of water. Is there something obvious that I'm missing?

Thanks in advance for any help.

Some people say that doing the backstroke through here is the easiest way.

If you swim through looking forward, just keep trying to keep your mouse facing forward and eventually you will make it.

A good place in the game to develop an ulcer, that's for sure, but it does get easier every time you have to go through

Thanks for the advice. I'll give it a try.
