Nature & Discovery.

Gray's Creek Conservation Area is the RRCA-managed wetland inside the City of Cornwall — 41 hectares of marsh and riparian habitat at the mouth of Gray's Creek into the St. Lawrence, with trails and a boat launch.

Roughly 25 minutes east in South Glengarry, Cooper Marsh Conservation Area runs the regional boardwalk-birding product on a 600+ acre St. Lawrence wetland with an observation tower; together with the Cornwall-based St.

Lawrence River Institute of Environmental Sciences, the cluster anchors birding and freshwater interpretation in the Cornwall area.

Nature & Discovery in Cornwall
01 — What to know

The brief.

Gray's Creek is the in-city anchor — accessible from the eastern edge of the Recreational Path, with shore-access trails, marsh viewpoints, and a small boat launch. Cooper Marsh is the destination birding wetland, best in spring (April–May) and fall (September–October) migration when waterfowl concentrations peak; the boardwalks may flood in high spring water and the parking is open daylight hours.

The St. Lawrence River Institute runs interpretive programming on river biodiversity and water quality from its Cornwall campus.
