Grand River.
The Grand River runs roughly 300 kilometres south from the highlands near Dundalk to Lake Erie at Port Maitland — designated a Canadian Heritage River in 1994 and the longest river entirely within southern Ontario. The Grand River Conservation Authority manages 11 conservation areas across a 6,800 square kilometre watershed: Belwood Lake, Brant, Byng Island, Conestogo Lake, Elora Gorge, Elora Quarry, Guelph Lake, Luther Marsh, Pinehurst Lake, Rockwood, and Apps' Mill.
A continuous network of rail trails connects the corridor — the Cambridge to Paris Rail Trail, the 47-kilometre Elora Cataract Trailway, the SC Johnson Trail, and the Grand Valley Trail running roughly 280 kilometres along the river. Whether you're walking limestone gorge trails at Elora and Rockwood, paddling the Class I flatwater between Cambridge and Brantford, or casting for brown trout in the Shand Dam tailwater near Fergus, this is some of the most accessible river-corridor terrain in the province.
Most of it is within an hour of the GTA, Hamilton, and Guelph. The lower Grand sits within the Haldimand Tract granted to the Six Nations of the Grand River.

Hiking
The Grand Valley Trail runs roughly 280 kilometres along the river from Lake Erie to the Dundalk highlands, maintained by the Grand Valley Trails Association. Inside the GRCA conservation areas, Elora Gorge carries trails along 22-metre limestone cliffs above the Grand, and Rockwood Conservation Area on the Eramosa tributary has glacial potholes and small caves that don't appear elsewhere on the watershed. Apps' Mill anchors Carolinian forest hiking near Brantford on the lower Grand, and Pinehurst Lake adds kettle-lake walking on the upper watershed.

The Cambridge to Paris Rail Trail runs flat and gravel-surfaced for about 30 kilometres along the Grand, the SC Johnson Trail continues the corridor between Brantford and Paris, and the 47-kilometre Elora Cataract Trailway connects Elora to Cataract on a former Canadian Pacific rail line. Together these trails make most of the Heritage River corridor walkable on continuous, family-friendly surface from Brantford north to the headwaters.

Five GRCA conservation areas carry frontcountry and RV camping along the Grand: Byng Island near Dunnville at the river mouth, Brant near Brantford on the lower Grand, Rockwood on the Eramosa, Elora Gorge above the limestone cliffs, and Pinehurst Lake on the upper watershed. Camping season runs May through mid-October at most areas; Elora Gorge and Rockwood pair camping with their gorge and pothole swimming features.

Luther Marsh Wildlife Management Area is a provincially significant wetland on the upper watershed — sandhill crane staging in fall and waterfowl through spring and fall migration. On the lower Grand, Apps' Mill Conservation Area holds Carolinian-belt forest birding near Brantford, and Pinehurst Lake adds kettle-lake nature interpretation on the upper watershed.
Read field guide arrow_outwardCycling
The same rail-trail network supports cycling along the Heritage River corridor: the Cambridge to Paris Rail Trail, the SC Johnson Trail south to Brantford, and the 47-kilometre Elora Cataract Trailway from Elora to Cataract. The Grand Valley Trail offers cycling-permitted segments along the river. Together they thread a near-continuous gravel/paved spine the length of the Grand, accessible from every major town on the watershed.

Cambridge to Paris is the most paddled flatwater run on the Grand — Class I water through riverside farmland with multiple GRCA put-ins — and continues from Paris to Brantford for a longer day or an overnight on the river. Three GRCA reservoirs cap the watershed for flatwater on still water: Belwood Lake at the headwaters above Shand Dam, Conestogo Lake on the Conestogo tributary, and Guelph Lake on the Speed. The Heritage River corridor runs roughly 300 kilometres from Dundalk to Lake Erie.

Elora Quarry Conservation Area is a former limestone quarry now operating as a designated swim area with limestone-cliff backdrops; Rockwood's swimming hole sits in a glacial pothole bowl on the Eramosa; and Byng Island carries a Grand River beach near the river mouth at Dunnville. Three different watershed swimming features — quarry, river pothole, river beach — within a short drive of each other.

Brown trout in the Shand Dam tailwater below Belwood Lake. The Grand River between Fergus and West Montrose is widely considered the best brown trout fly fishing in Ontario — a coldwater tailwater corridor sitting in Fisheries Management Zone 16. Below Caledonia the river warms and carries smallmouth bass, walleye, and pike on the lower Grand. Belwood Lake and Conestogo Lake reservoirs add stillwater pike and walleye on the headwaters.
Read field guide arrow_outwardHeritage & Culture
The 1994 Canadian Heritage River designation covers the full ~300-kilometre Grand River corridor — recognizing the river's natural and cultural significance from the Dundalk highlands to Lake Erie. The lower Grand sits within the Haldimand Tract granted to the Six Nations of the Grand River, the most populous First Nation in Canada. The river system itself is the heritage anchor at watershed scale; concrete heritage sites along the corridor are anchored within the towns the Grand passes through.
