The Cataraqui Trail is suitable for walkers, cyclists, horseback riders, snowmobilers and cross-country skiers. This trail covers 39 kilometres in South Frontenac. It originates from Smiths Falls, passes by Chaffeys Locks and along the northern side of Sydenham Lake before connecting with the K&P Trail just east of Harrowsmith. then runs westward to Strathcona.
Its surface consists in part of stone dust between Loughborough-Portland Boundary Road and Harrowsmith plus a small section west of Hogan Road. The remainder is loose gravel more suitable to cyclists on a mountain or hybrid bike. The eastern section provides the best vista because of the numbers of ponds and small lakes in a very natural environment.
