>>1208206It and Alberta are probably up there. Memeagonia is nice but it's getting too played out and touristy. Only some parts of AB and BC get touristy. Most other back/sidecountry mountainy places are completely ignored by most people. You can start from the highway and in 2 hours be on land that's never been touched or seen by a human in some places. If you get a couple hours from your car and fuck up badly you'll be in a deep world of shit and probably won't be found again or at least in one piece, Which is nice.
If backcountry isn't your thing the off road trails and logging road networks are nice.
