The name 'Forty Foot' is widely believed to refer to the 40th Regiment of Foot, which was stationed at the nearby Martello Tower in the 19th century.
Until 1974, the site was restricted to male swimmers only, with women officially barred from entering the water.
The James Joyce Tower and Museum is situated immediately adjacent to the swimming site.
The water depth at the jumping point is approximately 5 to 6 meters depending on the tide.
It is a popular location for 'dippers' who engage in cold water swimming for perceived health benefits.
The Forty Foot is a famous promontory in Sandycove, Dublin, known for its deep-water swimming in the Irish Sea. It features natural rocky limestone outcroppings used as entry and exit points for year-round swimmers. The site is a cultural landmark, famously appearing in the opening chapter of James Joyce's novel Ulysses. It remains a public, free-access location maintained by the local authority. The water is characteristically cold, with depth increasing rapidly from the edge of the rocks. Swimmers use iron railings and ladders attached to the cliffside to exit the water safely. It is a traditional gathering spot for the local community, especially on Christmas morning.

Bring a robe or changing towel, as there are no private changing facilities on the rocks.
Wear water shoes for better traction on the slippery, seaweed-covered limestone.
Check local tide tables, as entry and exit are significantly easier during high tide.
Jumping into the water without checking the current and tide conditions; attempting to climb the rock face where no ladder or railing exists.
Swimmers are expected to yield to those entering or exiting the water; maintain a respectful distance from others' belongings on the rocks.
