Saltspring Island is the largest, most populated, and most visited of the Gulf Islands chain of British Columbia, Canada. It was named by officers of the Hudson's Bay Company for the cold and briny saltwater springs on the north end of the island. Saltspring Island is located in the sheltered waters of the Southern Gulf Islands of British Columbia. Because of its close proximity to Vancouver Island, Saltspring is the most accessible of the Gulf chain of islands, with the most frequent ferry sailings on three routes to three ferry terminals. BC Ferries links Fulford Harbour with Swartz Bay (near Sidney), and also links Vesuvius to Crofton on Vancouver Island. There is a BC Ferries dock in nearby Long Harbour with a link to Tsawwassen, on the BC mainland. Floatplanes also link the village of Ganges to Vancouver and Seattle.
