Apodaca was designated a provincial park in 1954. The property was donated by Major J.S. Matthews, a noted Vancouver historian, as a memorial to his son who died at age 22. The park bears the name given to the islands at the entrance to Howe Sound by early Spanish navigators.
The park lies within the Coastal Western Hemlock biogeoclimatic zone and is home to Douglas fir, lodgepole pine, salal, and arbutus. Slope, drainage, and local weather patterns contribute to the presence of unique, rocky knoll vegetation, which is more typical of the Gulf Islands and Southern Vancouver Island.
Apodaca’s offshore waters support a variety of marine birds and mammals, such as marbled murrelet, harbour seal, and killer whale. Undersea and intertidal life include Pacific octopus, rockfish, and ochre starfish. The park also offers habitat for coast blacktail deer and a variety of birds.
