Limehouse Conservation Area

Limehouse Conservation Area is a protected stretch of the Niagara Escarpment near Limehouse, Ontario, within the Credit River watershed and crossed by Black Creek. It is notable for deep rock fissures and crevices that create a dramatic escarpment landscape, including the Hole in the Wall, where some narrow openings are reached by ladders from a trail. The area also provides habitat for redside dace, a fish listed as provincially threatened in Ontario. Alongside its natural features, it preserves remains of nineteenth-century lime kilns, opened in 1840 and operated until 1917, linking the site’s geology with the district’s industrial heritage.
