Tickets to attractions must be pre-registered on the website at TourismDay.ie. It is recommended to reserve tickets as early as possible as popular attractions are likely to book up quickly. Some sites are already sold out.

"Tourism is a wonderful teacher and I hope people take the opportunity of free admission to get out there and explore Ireland,” said former Nationwide presenter Mary Kennedy, who launched the event last week at MoLI, Dublin's new museum of literature.

The event will take place during the Easter school holidays to encourage families to explore their local attractions. It also coincides with Fáilte Ireland's new domestic marketing campaign, 'Keep Discovering,’ which highlights staycations, Independent.ie reports.

"Tourism Day is a chance for the public to explore a tourist attraction that they may not have visited before, or somewhere they would like to bring a friend or family member," said Eoghan O’ Mara Walsh, CEO of the Irish Tourism Industry Confederation (ITIC), which is organizing the initiative with the support of Fáilte Ireland.
