Sansana Spa at the Royal Marine Hotel

Sansana Spa at the Royal Marine Hotel is in Dún Laoghaire, County Dublin, overlooking the harbour town that has drawn Dubliners to the sea air for generations.

The spa offers treatments and thermal facilities in a hotel setting, making it an easy retreat after a walk on the pier or a day in the city, which is a short DART ride away. Treatment menus, day packages and access arrangements for non-residents change from time to time, so book and confirm details in advance.
