I have paddled the Missinaibi from Dog Lake to Moose Factory on James Bay. It is an excellent wilderness trip. We went mid July. Bugs? Yeah, it's WILDERNESS!  If your tripmates areg oing to let a few bugs affect your trip you need different tripmates.

You need skills to negotiate the rapids. This river CAN kill you. Haps book is the best guide and you can use his hand drawn maps to travel the river. There are no UTM coordinates however. I still have my Canadian topo maps and would be willing to sell them if you are interested. Contact me offline with a PM.

Once again the Missinaibi is one of the best river trips you can take in Canada, but it is a serious trip.  BTW, last year water levels got very low after July and the lower river was almost unnavigable.

Feel free to contact me if you have any specific questions.
