What's St Patrick's Day without a parade? In Galway, the city's theatrical heritage guarantees a spectacular one, with street performances by the Macnas theatre group, who will be marching with their giant puppets and Youth Ensemble. The parade is the climax of a three-day celebration across the city, featuring family entertainment, vintage amusements and an outdoor craft village.

Experience the energy of Dublin's St Patrick's Festival, the world's largest celebration of Irish culture. A weekend of festivities, from traditional music and dance performances, treasure hunts and talks, culminates on Monday with Ireland's biggest parade through the streets of the capital, which kicks off at noon from Granby Row. Highlights include pageants from Macnas, Bui Bolg, Spraoi and the Inishowen Carnival, as well as a special pageant to celebrate 40 years of Pavee Point, created by the Irish Traveller and Roma communities. 

Of course, the fun doesn't stop with Galway and Dublin. The whole country comes alive with their own twist on St Patrick's Day, with parades that represent the history behind each county.

For the devout (and those who love climbing hills), climbing Croagh Patrick is a St Patrick’s Day rite of passage. Every year, hundreds of people climb Westport’s holy mountain, where St Patrick is said to have fasted at the summit for 40 days. It’s a challenging climb but the views from the top are spectacular, with all of Clew Bay spread out before you. 

If you don’t want to climb all the way to the top, you can hike to the first viewpoint to get a sampling of the scenery and the smattering of tiny islands in the bay.  

On 15 March, the entire country will be on tenterhooks as Ireland squares off against Italy in their final Six Nations rugby championship match.
