When people travel to Calgary, they're usually doing so for one of two reasons: they're on their way to the mountains, or they're here for the Calgary Stampede.
We'd like to encourage those travellers to take a bit of time to explore Calgary - the area that lies outside the Calgary Stampede grounds. Summer or spring is the best time to play tourist, with nice warm weather and plenty of sunshine. And with many outdoor festivals and destinations like the Calgary Zoo, Fort Calgary and Heritage Park, it's a great place to bring the entire family.
