It was declared a World Heritage Site by UNESCO in 1986 and a national nature reserve by the Department of the Environment for Northern Ireland in 1987. In a 2005 poll of Radio Times readers, the Giant's Causeway was named the fourth-greatest natural wonder in the United Kingdom.

Much of the Giant's Causeway and Causeway Coast World Heritage Site is owned and managed by the National Trust. It is one of the most popular tourist attractions in Northern Ireland, receiving over 998,000 visitors in 2019. Access to the Giant's Causeway is free of charge: it is not necessary to go via the visitor centre, which charges a fee. The remainder of the site is owned by the Crown Estate and several private landowners.
