Banff and Jasper Natl Park campgrounds? Please advise

We had hookups at both Banff and Jasper (Trailer Tunnel and Whistler). Go to the website - check on availability. The cgs were full the entire time of our stay - we had reservations.

Go early to the parking lot of Moraine Lake (it is fairly small and very popular - so early is best) There is an uphill hike, but very doable, to one of the most spectacular sights you'll ever see.

Enjoy, it is so beautiful
