Sans Souci is connected to Taren Point, in the Sutherland Shire, to the south, by the Captain Cook Bridge over the Georges River.

Sans Souci took its name from a grand house built on Rocky Point Road on land bought in 1853, by Thomas Holt (1811–1888), a wool merchant and politician, for his German wife.

[citation needed] However, Holt thought that the area was too isolated so he built another house at Marrickville, overlooking the Cooks River, which he called The Warren.

A steam tram operated between Sans Souci and Kogarah in the 1890s which allowed people to enjoy bathing, boating and fishing.

[3] In 1937, a silent electric trolley bus was introduced that, until 1959, ran from Rockdale to Kogarah, Sans Souci and Dolls Point.

A shopping strip is located on Rocky Point Road, near the intersection of Sandringham St, including The Party People, various fast food outlets and the post office.
