There are many Xcountry Skiing trails in and around Calgary. South Glenmore Park and Bowness park are maintained by the City of Calgary parks department.
There is also cross country skiing at some City of Calgary golf courses (stay off the fairways/greens and on the designated trails - if people abuse the golf courses they will no longer stay open to winter activities):
Maple Ridge Golf Course - tracks set by skiers, sometimes by the City.
