In a Pickle in Canada

When you get to Saskatchewan River Crossing (between Banff and Jasper) head east. There's lots of random camping in the Nordegg area and campsites are usually not full either. I'd be surprised if you couldn't find somewhere to stay at the Bighorn dam, it's open for quadding and biking though so it can be noisy and busy. Not much for serviced sites though. It's a beautiful area, may favourite actually.

I believe whistlers in Jasper also has a few sites available on a FCFS basis. Good luck

Moved from RV Parks to RVing in Canada for additional input.

Not Red Deer. There are only 2 camp grounds and they will be fully reserved.

Go to Travel Alberta and have a look. There is a camp ground listing there by region that may get you off the hook. Note, these are provincial campgrounds only and finding 5 spots is going to be very difficult.

I feel for you. I will be entering the US around the 2nd or 3rd next week and no reservations anywhere. This will probably be a boondocking 4th of july.

Try the Hinton KOA just east of Jasper? Stay in the Columbia Icefields parking lot? Last time we were there one could park overnite. Try the first come first served campgrounds along the Icefields parkway? Wilcox near the ice fields (tight for big rigs I think)? There used to be (still?) gravel overflow parking areas where campers could overnite near Banff. Check with national park staff.

Oh, boy! Good luck. I feel for ya, but nothing I can do to actually help you.
