We stayed one night at Tunnel Mountain Campground in Banff National Park, but I really do wish we stayed longer! We stayed at the most basic of the three sites, (I believe it was number one) but still had a great time. The park provides you with FREE firewood for your fire pit, the washrooms are clean with great showers, and the view is top notch. You crawl out of you tent and have the Rocky Mountains peaking all around you. We even had a visitor at our campsite when a giant Elk decided to stop in and see what we were cooking for dinner!
Spent the next night at Lake Louise campground, however, we definitely preferred Tunnel Mountain!
