The Grasse River drains a wide swath of the northwest Adirondacks, running from its headwaters near Cranberry Lake northwest through Tupper Lake, Canton, and Massena before meeting the St. Lawrence. The upper reaches — the stretch that cuts through state land south and west of Tupper Lake — are classic Adirondack meandering water: slow current, alder thickets, beaver meadows, and long quiet paddles between put-ins. The lower river opens up considerably as it leaves the park, becoming a working river with dams, hydroelectric infrastructure, and a different character entirely. If you're looking for moving water in the northwest corner, start upstream — the middle and upper Grasse are where the paddling is.
