The trail itself crosses terrain ranging from placid farmland to the rugged Canadian shield. It is only intended for walking (hiking), snowshoeing, and cross-country skiing. No part of the Rideau Trail itself is owned by the Rideau Trail Association; the continuity of the trail is made possible by the generous permission of both private and public landowners and is enhanced by the existence of a special fund called the Rideau Trail Preservation Fund.

Each of the three hiking clubs of the RTA - Kingston, Central (Perth), and Ottawa, organize outings in all seasons of the year. They usually take place on the weekend and comprise an activity appropriate for the season, such as cross-country skiing and snowshoeing in winter and hiking in the spring, summer, and fall. Other activities are scheduled during the week or on some holidays.

There is a Guidebook of Maps and Trail description which is available to both members and non-members by mail from the RTA, some bookstores and outdoor stores.
