Ontario trails · Ottawa River Pathway
A 15.3-mile network in Ontario, with 74 ft of climbing. Reaches Chaudière Falls and other viewpoint/waterfall destinations. Managed by National Capital Commission.
Most of the climbing sits in the final third — 100% of the ascent, between mile 10.2 and mile 15.4. It gives back about 102 ft along the way, so it rolls rather than climbing steadily.
