We stayed at the campgrounds at Tunnel Mountain in Banff, Lake Louise, and Whistlers outside Jasper last August. Just paid for electric-only sites at each campground and never paid the firewood fee as we can certainly do without campfires for a week. All have potable water (multiple faucets scattered all across Tunnel Mountain) and multilane sanidumps. Didn't care much for the in-line, edge-of-paved road-style camping at Tunnel Mountain, but loved the shaded, cul-de-sac, elk-filled campground at Whistlers.
After two trips to those parks in the past 7 years, Jasper is our favorite among the four national parks (Banff, Jasper, Yoho, and Kootenay). Pyramid Lake, Maligne Canyon, Maligne Lake, Mt. Edith Cavell Road, Athabaska Falls, bighorn sheep, mountain goats, elk 10 feet from our trailer and in the middle of the Icefields Parkway, glaciers, rivers, more lakes, other waterfalls, fantastic geology, and on and on. Don't miss it!
