Passage Island is a small island near West Vancouver, British Columbia, and across from Bowen Island in Canada. The island is mostly woodland and cliffs. It marks the entrance to Howe Sound, and the ferry between Horseshoe Bay to Nanaimo regularly passes it. The island borrows a postal code, V7W 1V7, from the wealthiest community in Canada, West Vancouver. However, Passage Island is actually overseen by the Islands Trust and is part of the Greater Vancouver Regional District.
