Address: Off Percé, Quebec, Canada

Bonaventure Island sits in the Gulf of St. Lawrence about 3.5 km off the southern coast of the Gaspé Peninsula and roughly 5 km southeast of the village of Percé; the island covers about 4.16 km2. It is part of the Parc national de l’île-Bonaventure-et-du-Rocher-Percé, a protected area that groups the island with nearby Percé Rock.

The island has a long human history as a seasonal fishing port in the era of New France and later attracted settlers from southern Ireland and other places; commercial fisheries were important here into the 19th century. Bonaventure was declared a migratory bird sanctuary in 1919, and the province acquired the island by expropriation in 1971 before creating the national park in 1985.

Today the island is best known for wildlife rather than residents: it hosts one of the world’s largest northern gannet colonies and hundreds of thousands of seabirds overall. Visitors come for close views of nesting seabirds, coastal scenery and photography opportunities; boat trips and guided island visits run in the warmer months.

  • Northern gannet colony: One of the island’s highlights is its enormous northern gannet colony, counted at about 51,700 pairs in 2011.
  • Seabird diversity: More than 200 bird species have been recorded here, including kittiwakes, common murres, razorbills and Atlantic puffins.
  • Cliffs and coastal viewpoints: The island’s rocky coasts and vantage points offer dramatic views of seabird colonies and the surrounding St. Lawrence waters.
  • Views of Percé Rock: From parts of the island you can look back across the water to iconic Percé Rock and the town of Percé.
  • Wildlife observation: Bring binoculars and a telephoto lens for detailed views of nesting birds without disturbing colonies.
