Another place up there to consider is Wells Gray Provincial Park. It's just south of Bowron Lakes, and might be a nice add-on or replacement w/r/t fires. It's a pretty well-known paddling area--not as diverse an experience as Bowron, but good country. I was planning to go there in 2017 when they had all the fires which closed everything (did Bowron the year before, so looking for something different)--I was in Washington at the time.
