I don't know if you have checked the Open Roads Forum at http://www.rv.net/forum/ , which I recommended to you in a previous thread. The people who post on the Open Roads Forum have a wealth of information about travelling in recreational vehicles (RVs).
At this point Banff National Park's campgrounds operate on a first-come, first-served basis. Between looking up the Canadian national parks' web site at
and listening to their message on their toll free phone number (which is toll free only within North America) at
I found out Banff National Park intends to implement a reservations system for five of its campgrounds, starting in early August. The campgrounds at which the reservations system will be implemented are:
* Tunnel Mtn Trailer Court (starting Aug 4)
* Tunnel Mtn Village 1 (starting Aug 4)
* Tunnel Mtn Village 2 (starting Aug 4)
* Lake Louise Trailer (starting Aug 2)
* Lake Louise Tent (starting Aug 2)
According to "the Mountain Guide," which is a publication you get when you pay the national parks entry fee, the above mentioned campgrounds offer the following facilities:
Tunnel Mountain Trailer Court -- full hook-ups, flush toilets, showers, sani dump and disabled access -- 321 campsites in this campground
Tunnel Mountain Village 2 -- electrical hook-ups (not full hook-ups), flush toilets, showers, sani dump, disabled access -- 188 campsites
Tunnel Mountain Village 1 -- there are no hook-ups, but there are flush toilets, showers, sani dump, disabled access and an interpretation program -- 618 campsites
Lake Louise Trailer -- electrical hook-ups (but not full hook-ups), flush toilets, showers, sani dump, disabled access and interpretation program -- 189 campsites
Lake Louise Tent (which I'm sure you're not interested in) -- same facilities as Lake Louise Trailer, except there are no hook-ups -- 210 campsites
Of the above mentioned campgrounds, the Tunnel Mountain ones would be more convenient to grocery stores in Banff. Lake Louise is a small village with limited facilities for buying food for self-catering purposes.
You also may be interested Willow Rock campground. It's located east of Banff in Bow Valley Provincial Park, near the intersection of Hwy #1 and Hwy #40. It has electrical hook-ups, flush toilets, and showers. You can make reservations there. Here's a web site that provides an e-mail address that you can use to contact the staff of Bow Valley Provincial Park:
Mount Kidd is a private campground with full services for RVs. It's just off Hwy #40, half way between Hwy #1 and Kananaskis Lakes. It's more expensive than the campgrounds in the national and provincial parks. However, it does accept reservations, and I've read very complimentary remarks about it on the Open Roads Forum. Depending on how long your trip is and how efficient you need to be with your time, however, I think Mount Kidd is a little far from Banff to serve as a base for visiting Banff, Lake Louise and Yoho National Park.
Jasper National Park's reservation system already is operational, and you can access it via the web site mentioned above. Of the four campgrounds that offer a reservations service in Jasper National Park, I believe Whistlers and Wapiti would suit you best. Whistlers has 77 sites with full hook-ups and 100 sites with electrical hook-ups only. Wapiti has 362 sites with electrical hook-ups but not full hook-ups. Both Whistlers and Wapiti have flush toilets, showers, sani dumps and disabled access. Whistlers and Wapiti also are conveniently located with respect to grocery stores in Jasper townsite.
Hope that was helpful, but please ask the folks at the Open Roads Forum, because they really know what they're talking about.
