01 — Abstract

Peterborough sits on the Otonabee River in central Ontario, the largest city on the 386 km Trent–Severn Waterway between Lake Ontario at Trenton and Georgian Bay at Port Severn. The Peterborough Lift Lock — Lock 21 of the Trent–Severn, opened in 1904 and the world's tallest hydraulic lift lock at 19.8 m — anchors the city, with Locks 19, 20, and 22 (Auburn, Ashburnham, and Nassau Mills) carrying the canal through the urban stretch.

The Rotary Greenway Trail runs 22 km of paved riverside path from Lock 19 at Trent University past the Lift Lock through downtown to Lakefield. The Canadian Canoe Museum opened a new lakefront facility on Little Lake in 2024.

The Otonabee Region Conservation Authority manages Warsaw Caves, Harold Town, Mark S. Burnham, and Beavermead.

Petroglyphs Provincial Park (Kinomāgewapkong), co-stewarded with Curve Lake First Nation, sits a short drive north in Douro–Dummer Township. Peterborough is on the traditional territory of the Mississauga Anishinaabeg.

Hiking

Trent University's Symons Campus carries 1,500 acres of nature reserves with trails on both banks of the Otonabee River north of downtown. Inside the city, Jackson Park threads 105 ha of urban ravine forest under the Pagoda Bridge and forms the western anchor of the Rotary Greenway Trail. Harold Town Conservation Area runs 10 km of multi-use trails on the city's north edge, and Mark S. Burnham Provincial Park east of the city preserves a rare old-growth hardwood stand. Warsaw Caves Conservation Area in Douro–Dummer adds a karst day-hike option a short drive northeast, and the Ganaraska Trail's Wilderness Section heads north into the Kawartha Highlands.

Walking & Strolling

The Rotary Greenway Trail carries 22 km of paved riverside path along the Otonabee from Lock 19 at Trent University, past the Peterborough Lift Lock and downtown Little Lake, north to Lakefield. Del Crary Park sits on Little Lake at the foot of George Street and is the southern anchor of downtown waterfront walking. Jackson Park and the Pagoda Bridge add an urban-ravine route along Jackson Creek. The Lift Lock visitor centre and lock-grounds esplanade are walkable year-round and offer the closest viewing of the canal corridor.

Nature & Discovery

Trent University's 1,500-acre Nature Areas straddle the Otonabee on the Symons Campus, with managed reserves carrying interpretive trails through forest, wetland, and riparian zones. Mark S. Burnham Provincial Park east of the city protects old-growth hardwood — a rare south-central Ontario survival. Harold Town Conservation Area on the city's north edge and Beavermead Park on Little Lake add accessible nature-interpretation surface inside the urban footprint, and the Otonabee Region Conservation Authority publishes seasonal access notes for each.

Cycling

The 22 km Rotary Greenway Trail runs the Otonabee corridor on a paved multi-use surface from Lock 19 at Trent University past the Peterborough Lift Lock through downtown to Lakefield, making it the easiest entry point to cycling in the city. The Kawartha Trans Canada Trail picks up east of Peterborough and runs roughly 52 km on a former Canadian Pacific Railway corridor to Hastings, knitting into the Trans Canada Trail through Northumberland and Hastings counties. Together they make Peterborough a regional cycling node on the eastern Ontario rail-trail system.

Paddling — Flatwater

The Otonabee River and the Peterborough stretch of the Trent–Severn Waterway carry flatwater paddling through the heart of the city, with Locks 19 (Trent University), 20 (Ashburnham), the Peterborough Lift Lock at Lock 21, and Lock 22 (Nassau Mills) sequencing the urban canal. Launches at Beavermead Park on Little Lake and Del Crary Park downtown open into the Trent–Severn system; from there, paddlers can carry through the Lift Lock or continue upstream to Lakefield and the Kawartha Lakes chain. The Indian River through Warsaw Caves Conservation Area runs flatwater past karst kettle holes northeast of the city. Peterborough is also home to the Canadian Canoe Museum on Little Lake.

Freshwater Fishing

The Otonabee River, Little Lake, and the Peterborough stretch of the Trent–Severn Waterway carry warmwater fishing for walleye, smallmouth bass, muskellunge, and panfish under Ontario's Fisheries Management Zone 17 (Kawartha Lakes / Trent–Severn). Rice Lake, a short drive south, anchors the southern edge of the Kawartha system and is the regional walleye and muskie water. The Trent–Severn navigable corridor lets boaters move between the city and the Kawartha chain through summer; ice-fishing closes the system November through April.

Indigenous Experiences

Petroglyphs Provincial Park (Kinomāgewapkong, "the rocks that teach"), co-stewarded with Curve Lake First Nation, protects what Ontario Parks describes as the largest known concentration of ancient Indigenous rock carvings in Canada — approximately 900 figures carved into a single marble outcrop, housed inside a protective glass-walled building near McGinnis Lake in Douro–Dummer Township. The Whetung Ojibwa Centre at Curve Lake First Nation runs a long-standing gallery and cultural centre. Trent University's Nogojiwanong campus has hosted the oldest Indigenous Studies department in Canada since 1969. Peterborough is on the traditional territory of the Mississauga Anishinaabeg.

Heritage & Culture

The Peterborough Lift Lock — Lock 21 of the 386 km Trent–Severn Waterway, opened in 1904 and the world's tallest hydraulic lift lock at 19.8 m — sits at the eastern edge of downtown with a Parks Canada visitor centre and a walkable lock-grounds esplanade. Three other Trent–Severn locks (19, 20, and 22) carry the canal through the city. The Canadian Canoe Museum opened a new lakefront facility on Little Lake in May 2024, holding what the museum describes as the largest collection of paddled watercraft in the world. Hutchison House Museum (1837) and Lang Pioneer Village add depth, and Mark S. Burnham Provincial Park preserves old-growth hardwood forest east of the city.

Geology & Discovery

Warsaw Caves Conservation Area in Douro–Dummer Township, about 25 km northeast of the city, carries seven explorable caves on a karst landscape on the southern edge of the Canadian Shield. The Indian River cuts through the property past kettle-hole formations and the cave entrances. The Otonabee Region Conservation Authority manages the site and publishes seasonal closures for bat hibernation. The caves are at-your-own-risk exploration; ORCA recommends two flashlights, a helmet, and sturdy footwear. Peterborough is the gateway city for the closest accessible cave system to the GTA.
