I have not stayed anywhere other than what looked like establish places in the Sundial PMA. I'm always looing though. I found a few places that would be suitable for a hammock, though not much camp life, or certainly not more than 2 people. I see two big issues with finding a place along the Beartrap. 1st is it goes from marsh swamp grass to thick alder/birch shrubs. From there dense black spruce and birch don't make for any clearings that I have seen, especially for any kind of camp. 2nd any high ground is usually along the portage. For a PMA the Beartrap is a highly used waterway. It could be done, but I don't think it would be enjoyable. Can't comment on the fishing in the Beartrap.
