About This Location

Cape St. Mary's on Newfoundland's Avalon Peninsula is home to one of the most accessible seabird colonies in North America. Bird Rock, a massive sea stack just 10 meters from the mainland cliff edge, hosts over 24,000 Northern Gannets along with thousands of Common Murres, Black-legged Kittiwakes, and Razorbills.

The experience of standing at the cliff edge, eye-level with soaring gannets and surrounded by the colony's roar, is unforgettable. A short trail from the interpretive center leads through coastal barrens to the colony viewpoint, requiring no boat ride — a rarity for seabird colonies of this caliber.
