Banff stealth camping

Any recommendations on stealth/cheap camping in Banff in early August?

Our Volvo station wagon is stealth ready and usually we bring our tiny travel trailer (also stealth ready and fully self sustaining) but it looks like we might have to leave it...

Thanks!

The trailhead to mt.louis is a nice quiet spot. The overflow parking for Lake Louise may be a good option as well. If you're in Canmore, I hear that the visitor center is laissez fare.
