Caledon.

Caledon spreads across 688 square kilometres of the Niagara Escarpment and the Oak Ridges Moraine in the northern half of Peel Region, the GTA's escarpment-and-moraine adventure backyard north of Brampton. Forks of the Credit Provincial Park covers 282 hectares where the West Credit River meets the main Credit at the 22-metre Cataract Falls, and the Cheltenham Badlands — 36 hectares of exposed Queenston Shale (Ontario Heritage Trust property, managed by Credit Valley Conservation, with on-surface walking prohibited and a boardwalk viewing platform open by reservation) — sits a short distance south on the same escarpment slope.

The Caledon Hills Section of the Bruce Trail runs 71 kilometres through the town and into Mono, passing the Cheltenham Badlands trailhead, Forks of the Credit, Belfountain Conservation Area, and Glen Haffy. The 36-kilometre Caledon Trailway rail-trail crosses the town from Terra Cotta in the southwest to Palgrave in the northeast as part of the Trans Canada Trail.

Albion Hills Conservation Park, north of Bolton on the Oak Ridges Moraine, carries roughly 50 kilometres of trails, a 200-plus-site campground, and groomed cross-country ski trails with on-site rentals. The Credit River below the Forks is one of southern Ontario's premier migratory rainbow trout (steelhead) and brown trout reaches.

The Niagara Escarpment was designated a UNESCO World Biosphere Reserve in 1990. Caledon sits on Treaty 19 (Ajetance Purchase) territory of the Mississaugas of the Credit First Nation.
