From a tourism point of view, the 1.7 million ferry and cruise passengers that pass through the Port every year bring considerable revenues to all facets of the Irish economy. In addition, the rising throughput at Dublin Port is good news for the economy as a whole, generating employment and economic activity both for the surrounding areas and for all the businesses and communities that depend on the efficient service that the Port provides.

Dublin is Ireland's most popular port with cruise liners. The cruise liner industry at Dublin Port has continues to grow with 88 cruise liners hosted during the 2010 cruise season. These liners carried in excess of 65,000 high-spend passengers and 28,000 crew members. Dublin Port Company's work in promoting Dublin as a leading cruise destination has generated a major cash boost of between €35 million and €50 million for the local economy through direct and indirect spend.
This steady rise in income for the economy generated by the cruise sector is offsetting the relative decline in ferry passenger numbers caused by increased competition from the low-fares airlines. However, it must be noted that ferry passengers not only stay longer, but also travel far further into the country; with a resulting higher spend on regional tourism attractions, particularly in the West of the country.
These visitors, along with passengers on cruise liners, are hugely valuable to Ireland's tourist industry and demonstrate that Dublin Port is a crucial destination for both freight and passenger traffic.
