Calgary has a reliable public transit system that is easily accessible and affordable. You can also consider renting a car to explore the region outside the city. If you are going on a day trip to Banff National Park, organized tours are the most convenient option. Budget around $50-$80 CAD for car rental or $80-$100 CAD for a guided tour.
If you have more time, consider visiting the Calgary Stampede or taking a day trip to Drumheller's Royal Tyrrell Museum. If you have less time, prioritize the downtown area and Banff National Park. Always check the weather conditions beforehand and dress accordingly.
The main airport serving Calgary is the Calgary International Airport (YYC), located approximately 17 km/11 miles from downtown Calgary. It is easy to access by taxi, shuttle, rental car or the express bus service (Route 300) which costs around $10 CAD per trip.
