How are the portages and creek passage on this route in the Fall usually? We will plan on staying on Glacier for one night.

This is a nice stretch of lakes and portages. Plan on a bit more time than the map would suggest. The portage into Glacier from the north is a steep climb. Be careful at Louisa Falls, as a slip would be a major fall.

did them late last August. I dont think water levels have a big affect aside from super high spring levels......so you should be good.
We did Louisa to Mac. Some of them are a little obscure, but are found easily with a touch of searching, like the Arp, Star ones. In the other thread when Sedges mentions the "wrong step" portage, I believe that is the one between Dumas and Fauquier. You place one foot in front of the other on a 4 inch ledge along a 45 degree rock face that slides down into a creek.......tread lightly my friend. Somewhere along that route we lined loaded canoes down a rock stream also.....cant recall where. Kip has it on Youtube....see if I can find it.
All in all, not real difficult but as others mentioned, slower going than you would expect.
I believe I preferred going up Louisa Falls with the canoe more than I would going down. I have that one on video but not loaded to Youtube yet. Found the Kip video Lining rocky creek

I loved the McEwen creek. Very peaceful through there. And yes, hope for no rain the day you portage into Agnes from Louisa. It's steep and slick if wet.

Bored tonight between calls.....loaded some video.

I found the left side of the falls going down better at least in pouring rain.

The left side going down (or the south side) is where the portage is located.
