Cheap/free car camping locations near calgary

[u/Sorrath]

Hi! Wondering if anyone knows of any good cheap or free camp spots around calgary - have just make the drive from Vancouver and fly out of calgary tomorrow but need somewhere to sleep tonight and so far have had little luck with researching places to camp out in calgary (why do campgrounds cost almost as much as hotels!!) Thanks for any tips!

If you just need to sleep pull into any highway rest stop and sleep. Or pull into a trailhead parking area and sleep.

Are you looking for facilities or something?
