Destination guide
Ottawa: Canada's capital, and the world's largest skating rink
Ottawa is a compact capital with free national museums, Parliament Hill above the river, and a canal that freezes into a 4.8-mile skateway every winter. Gatineau and the Quebec hills are ten minutes across the bridge.
Best time to visit: May for the tulip festival, June to September for warm weather and Canada Day on 1 July. February for Winterlude and the canal skateway, when it is cold enough to freeze — which is not guaranteed every year.
