Paddling — Sea & Coastal.
The Brock Isles route — Ontario Trails Council Thousand Island Route 9 — runs through the eastern end of the Thousand Islands archipelago, where the Brockville Narrows scatters 70 islands and 60 shoals just offshore from downtown. Day-paddle launches from the Brockville Henry Street boat launch reach Stovin Island and a string of Brockville municipal park islands offering day-use and camping.
The brief.
The Brock Isles cluster is well-suited to relaxed day-paddling and short overnight trips, with multiple short crossings and sheltered routing through the islands. Stovin Island is a flagship day-use island.
Thousand Islands National Park's main mainland visitor centre and most paddler-access cabins lie further downstream around Mallorytown Landing in the Leeds and the Thousand Islands township — accessible from a Brockville base as a multi-day extension, but not a Brockville day-paddle product. The St.
Lawrence is open commercial-shipping water — paddlers should plan for ferry traffic, freighter wakes, and changeable wind. Best season is June through September, with July and August the peak Thousand Islands paddling months.
