Welcome to Thousand Islands

The narrow, slow-paced Thousand Islands Parkway dips south of Hwy 401 between Gananoque and Brockville, running along the river for 35km before rejoining the highway. The scenic journey winds along the pastoral strip of shoreline offering picture-perfect vistas and dreamy picnic areas. The St Lawrence Bikeway bicycle path, part of the riverside Waterfront Trail between Niagara-on-the-Lake and Cornwall, extends the full length of the parkway.
