Tunnel Mountain exists of 3 campgrounds, of which Village II Campground provides full hook-ups. It is a huge Parks Canada campground, having 222 RV sites. Currently roads are being paved all around, and parking & hooking up the camper is easy. Sites are close by one another, yet the site is quiet. Except for the passing trains... a first time experience for us. Accomodation buildings are basic, yet provide the services one may require. September is not high season, so the campground was not over-populated. For Banff, this surely is a recommendation, when RV-ing through the Rocky Mountains.
