Destinations such as the Canadian Rockies are especially attractive, as outfitters make it easy to arrange guided hiking, biking, white-water rafting, and horseback riding excursions simply by talking to your hotel's concierge. Destinations on the Pacific coast provide opportunities to learn to sea kayak or to journey out onto the seas to view marine wildlife, while the prairie provinces feature guest ranches and Old West activities.
Remember that even children traveling with parents will be required to have some sort of official ID. This can either be a passport or a birth certificate. Children under the age of 18 traveling alone to Canada will need to have a signed letter from parents.
If your travel plans take you to Vancouver, consider buying a copy of Frommer's Vancouver with Kids (Wiley Publishing, Inc.).
Bringing Children into Canada -- If you are traveling with children under age 18, you should carry identification for each child. Passports are best, though birth certificates are still accepted, though this may change. Divorced parents who share custody of their children should carry copies of the legal custody documents. Adults who are not parents or guardians should have written permission from the parents or guardians to supervise the children. When traveling with a group of vehicles, parents or guardians should travel in the same vehicle as the children when arriving at the border. Customs officers are looking for missing children and may ask questions about the children who are traveling with you.
