For the ultimate city view hop aboard a WWII biplane and let yourself be expertly piloted over Ottawa. The age and heritage of the Waco UPF-7 plane might not mean much to kids, but even the most history averse will love its cool retro looks, funky propellers and the fact that you get to wear a vintage helmet and goggles to fly. Each plane carries two passengers and the experience of open-cockpit flying is exhilarating. First Flight Tours take between six and eight minutes, good with younger kids. There are also Ottawa River Tours and hugely popular Parliament Hill Tours, both lasting up to 15 minutes. And the stunning half hour Eco-Tour over Gatineau Park, Québec and Ontario is the one to book for conscientious older kids and teens.
