Gulf Islands National Park Reserve is not one contiguous area of land, but rather is scattered across 15 larger islands, and many more reefs and islets besides. Much of it can be found on the bigger southern Gulf Islands, such as North Pender, South Pender, Saturna, and Mayne, though there are also parts further south on Sidney Island, Isle-de-Lis (Rum Island), and D’Arcy Island.
The best way to explore is by boat. Tours to the islands depart from Vancouver and Victoria and typically include seaplane transfers, boat cruises, and kayaking excursions. Wildlife-spotting is a big draw, though there are many hiking and kayaking routes as well as swimming spots within the park too.
