Calgary is serviced by several public transit options like buses, trains, and taxis. The cost of public transportation for a day is around $10, and it takes approximately 40 minutes from the airport to the city center. It is recommended to rent a car if you plan to visit surrounding areas.
If you have more time, consider visiting the Calgary Zoo or taking a trip to Banff National Park. Make sure to have comfortable walking shoes as there is a lot of walking involved in most attractions.
Calgary International Airport (YYC) is just 20km northeast of downtown Calgary, and is the busiest airport in Alberta.
