A wildlife-rich Gulf Island sanctuary and the largest seabird colony in the Strait of Georgia.
Mitlenatch Island Nature Provincial Park
Mitlenatch Island Nature Provincial Park is a small but ecologically significant protected area in British Columbia, Canada, centered on Mitlenatch Island in the northern Strait of Georgia. Located roughly 30 kilometres northeast of Courtenay within the Strathcona Regional District, the park encompasses a modest upland area along with a larger surrounding marine foreshore, creating a refuge where seabirds, marine mammals, and intertidal life thrive largely undisturbed by human activity.
The park is best known for hosting the largest seabird colony in the Strait of Georgia, a distinction that shapes both the island's protected status and its management as a strict nature reserve under the international IUCN system. Glaucous-winged gulls, pelagic cormorants, pigeon guillemots, rhinoceros auklets, and black oystercatchers return each spring to breed on the rocky shoreline and grassy uplands. The surrounding waters also shelter harbour seals, sea lions, river otters, and the occasional killer whale or harbour porpoise, reinforcing the park's reputation as a compact but remarkably productive coastal ecosystem.
Because the island is only reachable by boat and most of its interior is closed to the public to safeguard nesting birds, the park functions more as a sanctuary than a typical recreational destination. A few permitted shoreline trails and a gull viewing blind offer carefully managed points of access, allowing visitors to experience one of the Salish Sea's most important seabird and marine habitats while keeping disturbance to a minimum.
