The Cataraqui Trail is a multi-use trail on the former CN rail line from Smiths Falls to Strathcona, just north of Napanee. The trail is 104 kilometres long and begins at the south end of Smiths Falls. Along its route, it passes through a number of communities including Portland, Chaffeys Lock, Sydenham and Harrowsmith.

Cycling, walking, and horseback riding are permitted uses during the spring, summer and fall. During the winter months when there is sufficient snow, the trail is groomed for snowmobiling and is open to snowmobilers bearing a current Ontario Federation of Snowmobile Clubs trail permit. It is also open in the winter to cross-country skiers and walkers. Motorized vehicles such as cars, ATVs and motor bikes are not allowed on the trail.

The Trail is managed by the Cataraqui Trail Management Board and maintained by community volunteers. Memberships and donations help to keep the Trail open. Income tax receipts are issued for all memberships and donations. The other way to help keep the Trail open is to volunteer some of your time.
