Flight
The closest airport is the Calgary International Airport. It is a 1 hour 10 minute drive from the airport to the city of Canmore (where the reception will be). Rental cars are the best option if you would like to explore the national park, but shuttles are also available.
Hotel
While the ceremony is in Banff, the reception is 20 minutes away in Canmore. We recommend staying there, but you could also stay in the town of Banff if you wish. There are many options ranging from hotels, to apartments, to houses. Expedia.com, booking.com, and hotels.com have offered the best prices and show many private airbnb's as well.
