Agde can be reached by TGV SNCF train direct from Paris or Lille whilst the closest airports are Béziers-Cap d'Agde en Languedoc, with direct budget airline services to the UK and Scandinavia, or Montpellier-Fréjorgues.

Cap d'Agde is one of the largest leisure ports on the French Mediterranean. Development as a tourist resort started in the 1970s before which time the only buildings at the Cap were small houses typically used for weekends by local people.
The Musée de l'Ephèbe houses the bronze nude statue known as "l'Ephèbe d'Agde" ("the Youth of Agde"). The statue was discovered in the River Hérault and was housed in the Louvre Museum prior to suitable facilities being made available in Cap d'Agde to house it.
