I would have to say that easily the best fishing times I've ever had in my life were the 20 or so week long trips to Kipawa, there's just some magic there that stays with you for months after being there. Camped there the first few years and then stayed at Corbeau lodge several times, now privately owned by Eric Lindros and then once we got an opening stayed at Alwaki lodge for the rest of our visits. That was a 14 mile boat ride.
I still follow the Kipawa forum and this was recently posted. The quite famous 230 acre Topping Retreat that once was sold to the owner of the NY Yankees is again up for sale for the great price of only $8.9M. This place once graced the Canadian $10 bill, was home to a couple of movies and was visited by many famous movie stars like Gregory Peck and Katherine Hepburn. The scenery is magnificent situated at the end of Kipawa River where it empties into Lake Temiscaming. There's close to a hundred pics of the property, well worth going through. Also a few good pics from upstream on Google Earth of some of the rapids. Cheers
