With stunning views of the St. Lawrence River at the eastern edge of the 1000 Islands, Blockhouse Island is a beautiful park that juts out into the mighty St. Lawrence River making it a lovely scenic setting to drive, walk or cycle around. Relax by the river’s edge on Blockhouse Island and watch the colourful pleasure crafts cruise by, enjoy an ice cream cone or have your picture taken in a giant Adirondack chair. The cargo ships travelling the International Seaway are so close you can wave to the crew. Walk through Canada’s first railway tunnel, traveling 500 metres under the City. The tunnel’s south portal is located on Blockhouse Island and was re-opened in August 2017 from end to end with a colourful light and sound show highlighting the tunnel walls and mineral deposits. Blockhouse Island is also home to the Brockville Municipal Harbour. Public washrooms, a licensed outdoor bistro, souvenir shop and visitor information centre are all located in the James A.C. Auld Harbour Services Building. The island, joined to the mainland by a causeway, features special events in summer such as hydroplane races, vintage car show, poker run lunch stop, beerfest, etc.
