Ottawa is a great city for walking and cycling too. Most of the sights in the Downtown area are within walking distance of each other. Taxis, tour buses and riverboats are all other ways of seeing the city.
The airport, Ottawa International, at which flights to Ottawa land, is well connected by public transport as well as by taxi and limousine. There are hotel shuttle and limousine services available to the centre of Ottawa. Buses depart from outside the Arrivals area. Taxis are also available.
Considering it’s the capital’s airport, Ottawa Macdonald-Cartier International is not a big air field. However, travellers who have used it have nothing but praise for it. It’s a much-garlanded and admired airport. Among other awards, it was ranked number one in the world in the two to five million passenger category by Airports Council International in 2011.
Macdonald-Cartier International is part of the busy air corridor between Ottawa, Montreal and Toronto, known as the Eastern Triangle. Most of the flights that arrive at the airport are from other parts of Canada and the US. However, there is a London Heathrow-Ottawa route and one from Frankfurt too.
With more than four million passengers each year, it’s Canada’s sixth-busiest airport. Macdonald-Cartier International is a focus city for Air Canada and a base for First Air, the Northern Canadian carrier. It has United States border pre-clearance facilities, an important feature that can save travellers a little time.
