The Grand Valley Trail is 275 km long and runs from Rock Point Provincial Park on Lake Erie which is south of Dunnville to Alton not far from Orangeville where it links by a side trail to the Bruce Trail. It is managed by the volunteer group, the Grand Valley Trails Association. Hikers are able to identify the main Grand Valley Trail by the white blazes approximately 5 cm wide by 15 cm high. The trail is well-maintained and has good relationships with the nearby landowners. A GVTA Guide Book, 6th ed. 2006 was published but is kept up-to-date by a list of trail and road changes by the affiliated organization.
