Fairly striaght forward we put in at Dan lake, kicked out the passengers at the dan->mcKewan portage, paddled the boat through solo, and picked them up on the other side, then paddled down to the mckewan->horse lake portage. It's a little soft there, but there is a plank you can stand on to load/unload. The portage is in pretty nice shape, they added some new boardwalks this season (2021).
While we were there we checked out site #5, which is pretty sweet, and stayed on site #7 for two days.
This was a nice easy trip to introduce some new campers to the concept of back country camping. Getting to/from the site from Dan lake access only took about 2 hours, and that was with a lunch break.
Technically it's a 2 portage route, but you can skip the one from Dan>McKewan when the waters high and the boats not sitting to low. It's a bit tricky, and the rocks are covered in paint chips, but i've nagivated it a couple times now this summer without any mishaps.
