The Navy Island Nature Preserve and Conservation Easement are located in the northwest region of Navy Island, in Passamaquoddy Bay. The island is located less than 1.5 km off the south-west shore of St. Andrews, New Brunswick. This preserve can easily be viewed from the mainland, specifically from the town of St. Andrews. The island itself serves as a scenic backdrop to the town and is admired by residents for its unspoiled beauty. The nature preserve covers 19.7 hectares (48.7 acres) and borders the Leigh Williamson Conservation Easement, consisting of 5.3 hectares (13.1 acres), which is located on the north-west tip of the island.

The preserve and easement hold great value aesthetically, historically, and ecologically.


Comprising a large portion of Navy Island, the Navy Island Nature Preserve shares the historical significance of the area. The island was inhabited by loyalist settlers even before there was a formal settlement known as St. Andrews. Evidence of these early settlers includes remnants of cellar holes, building foundations, and a cemetery located at the north-east boundary of the preserve.


Navy Island is one of the most ecologically significant areas in the Maritimes. The significance is related to the great rise and fall of the Fundy tides. Rapid changes in water level pushes nutrients to the surface supporting many species of birds and creating a key habitat for many coastal and migrating bird species throughout the year.

Access and Activities

The island is accessible only by boat or kayak from the St. Andrews wharf. There are marked hiking trails on this preserve; however, these trails are not fully developed.  Improvements are planned for the future.
