Jasper & Banff!
mxvp,
A couple years ago (before we had the camper) we made a run down from Prince Rupert through Prince George and Jasper into Banff/Canmore then down BC 93 into Radium Hot Springs, Whitefish MT and Missoula MT.
The run from Tete Jaune Cache (T John Cash) through Radium Hot Springs was drop dead beautiful. We were running fast in the cooler off season and it was a motel trip for us so I don't have good information on camp areas but check B.C. Parks at:
http://www.env.gov.bc.ca/bcparks/ for the provincial parks. There's probably another site for national parks but I don't have it bookmarked. I do remember one nice looking campground near Jasper.
The Drive B.C. site at:
http://www.drivebc.ca/ is a great site too. It gives road conditions, including construction, and you can get to B.C. Weather from there too.
We didn't hit Glacier Park on that run but it's easy access off of US 93 via US 2.
I haven't looked but I'm pretty sure the Alaska Milepost covers the run through Banff/Jasper parks. If so, it would be a good resource for you on camp areas, fishing, sights, etc.
The folks in Jasper said May was the best time of year to visit since the bulk of the tourists haven't shown up yet and the weather usually isn't terrible.
Not sure where Ta Ta Creek is so hope I haven't gotten too far off track here.
We'll look forward to your trip report with lots of pics and information on good spots to camp!
Happy Trails,
