Louisa, I have been there four times: I paddled from Allanwater Bridge up to Smoothrock and flew out (a great trip but becoming quite popular); The Brightsand River loop from Allanwater down through Kawaweogama Lake and Sesenaga into Wapikamaski and then north on the Brightsand back to Allanwater; the Flindt river east of Savant lake to Smoothrock Lake, and the Misehkow River.  Anyone traveling in Wabakimi should have some competence in moving water as it offers classic shield pool and drop rivers with some nice long rapids thrown in.  Portages can be difficult to find due to very little use.  Taking the Via Rail train in and out with your canoes and gear is a great experience and not too expensive.  The services of an outfitter for maps, traveling arrangements and permits is highly advised.  The park is absolutely beautiful and offers some of the best fishing I have had anywhere.  Feel free to message me if you want more info.
