Sidney Island is one of the southern Gulf Islands located in Haro Strait between Vancouver Island and the mainland coast, about 45 miles (73 km) south-southwest of Vancouver and 2.8 miles (4.5 km) east of Sidney, British Columbia.
The island is located between Sidney Channel to the west and Miners Channel to the east. The Sidney Spit is on the north end of the island and is known for salt marshes, tidal flats, beautiful sandy beaches, and backcountry camping. The northern end of the island including the spit is part of the Gulf Islands National Park Reserve. It was formerly the Sidney Spit Marine Park under provincial jurisdiction. Most of the southern part of the island is private land.
The spit is accessible only by boat and there are 21 public mooring buoys available, as well as limited space on the government dock. A walk-on ferry operates from the town of Sidney during the summer months. There are 26 walk-in, backcountry campsites available on the spit but no potable water. Read more here and here.
