With 150 km (93 miles) of recreational paths, the world's largest naturally frozen skating rink in the winter, 850 parks, and access to three major waterways, Ottawa is a joy for outdoor enthusiasts. As well as being home to the Government of Canada, Ottawa is a high-technology centre, and boasts more engineers, scientists and PhD graduates per capita than any other city in Canada. It's a great place to bring up a family and a fascinating city to visit.
