The park contains one of the last remaining examples of old-growth sugar maple and hickory forests in the Montreal region.
During spring, the park’s low-lying areas function as essential natural retention basins for snowmelt.
The site hosts a specific 'educational' trail section featuring informative panels about local forest succession.
A portion of the park is designated as an ecological reserve to protect sensitive plant species.
Bois-de-Liesse Nature Park is a 159-hectare protected area in Montreal, distinguished by its significant mature maple-hickory forests and diverse wetland ecosystems. The park serves as a critical biological corridor connecting the Prairies River to the surrounding urban landscape. It features over 13 kilometers of multi-use trails that accommodate hiking, cycling, and cross-country skiing. The terrain consists of flat, accessible paths winding through marshlands and dense woodlands. Seasonal floodplains are a defining geological feature of the site. Visitors can observe various bird species, including pileated woodpeckers and raptors, throughout the wooded interior. The park is managed by the City of Montreal as part of a network of natural spaces preserved for biodiversity.
The wooden boardwalk sections that cross the marshland areas provide the most distinct vantage points.
Bring waterproof footwear if visiting during the spring melt or after heavy rainfall, as trails can become muddy.
Use insect repellent during the summer months, particularly near the wetland and marshy areas.
Consult the trail maps at the entrance to distinguish between the dedicated cycling paths and the walking-only forest trails.
Do not attempt to traverse the swampy or marshy sections off-trail, as they are protected habitats and pose safety risks.
Ski trails are groomed and maintained exclusively during the winter season.
Stay on marked trails to protect fragile woodland vegetation and sensitive animal habitats.
