Why Visit
Crothers Woods lets you escape into 18 hectares of mature forest and winding trails just minutes from the city’s core. It’s where you’ll actually forget you’re in Toronto, especially when spring wildflowers bloom or coyotes prowl at dusk.
What Makes It Unique
Unlike most Toronto parks, Crothers Woods is an actual forest ecosystem, not a manicured greenspace. The network of singletrack trails is fully legit for mountain biking and trail running, with genuinely challenging sections and rewarding Don River views. Wildlife encounters are surprisingly common, setting it apart from busier ravines nearby.
Crothers Woods is one of Toronto's most significant urban natural areas — 18 hectares of mature forest in the Don Valley, one of the largest intact urban forest patches in the city. The forest sits on the west slope of the Don Valley, accessed from Bayview Avenue, and extends from the top of the valley slope down to the Don River floodplain (Cottonwood Flats).\n\nThe trail network in Crothers Woods is more substantial than most Toronto ravine parks — several kilometres of maintained trails ranging from wide gravel paths to narrow singletrack routes popular with mountain bikers. The Toronto and Region Conservation Authority manages the natural area, and the trails are marked with clear signage at the major junctions.\n\nThe ecological value of Crothers Woods is significant. Native plant species documented here include trout lily, trillium (Ontario's provincial flower), wild ginger, and bloodroot — spring wildflowers that indicate relatively intact forest floor ecology. The forest is part of Toronto's urban wildlife corridor; coyote sightings are regularly documented by the City's urban wildlife program, and white-tailed deer, red foxes, and a wide variety of bird species use the area year-round.\n\nThe Cottonwood Flats at the base of the slope — accessible via the valley trail — provide a striking visual contrast: flat, open floodplain meadow with tall cottonwood trees, a different habitat entirely from the forested slopes above. This habitat diversity makes Crothers Woods excellent for birding, particularly during spring and fall migration.
