If I understand you correctly, Viewranger even shows a path where you want to go. There are many options, simply make sure to find a bridge over the river Elchaig. It's more like a swim than hopping stepping stones to get over it. I crossed it much further upstream at the Iron Lodge where there is a bridge and fording it there would not have been a sensible idea.
Also, there is nothing wrong with checking out the Falls of Glomach if you haven't seen them before. In my books, that is. If you meet fellow CWTers they might start talking about the Falls. I skipped them on the CWT (coming from Alltbeithe) because I wasn't aware how nice they were (and due to feet and fitness issues. I checked them out on a later trip).
Enjoy
