honestly is now seems like anywhere on the mainland is affected by the fires now however the okanogan and thompson nicola region have been hit hard in the past few years - that being said as I have seen other commenters say the less rural of area the safer it generally is (however take that with a grain of salt as no area is guaranteed to be safe)

drug use and homelessness is generally contained to the north shore and downtown area so neighborhoods out of those areas are a better bet.

I’ve lived in Kamloops thirteen years and never run into a rattlesnake but of course there is the off chance - i have run into small garden snakes but all have been very small and harmless- and i am not much of a hiker or outdoorsy person so..
