Trent Hills.

Trent Hills is the Northumberland County municipality where the Trent-Severn Waterway runs through three river villages — Campbellford, Hastings, and Warkworth — and where the Ranney Gorge Suspension Bridge crosses the Trent River below Ranney Falls connecting Old Mill Park in Campbellford to Ferris Provincial Park's 198 hectares and roughly 10 km of gorge-edge trails. Five Parks Canada lockstations sit inside the boundary: the Lock 11/12 flight at Ranney Falls and Lock 13 at Campbellford, Locks 16/17 at Healey Falls, and Lock 18 at Hastings.

The Trans Canada Trail follows the river corridor between Hastings and Campbellford, and the Northumberland County concession-road grid carries low-traffic road cycling out into farmland between the three villages. Most of it is a short drive from Peterborough or a few hours east of Toronto via the Highway 401 / Highway 30 corridor.
