Today marks the start of the road to Paris, Bordeaux, Lille and, hopefully, Paris again as Martin O'Neill's men begin the first of their warm up games against Switzerland at the Aviva Stadium.
And after a somewhat quiet few months since the hysteria that surrounded the two-legged play-off win over Bosnia and qualification for Euro 2016, the preparations will step up a gear off the pitch too.
Watch Catalpa's Ireland Euro 2016 song 'Irish To The Core' from 50 seconds:
Iconic moments from tournaments in the past are more often than not accompanied by foot-stamping tunes like Give It A Lash Jack, We're All Part Of Jackie's Army or Joxer Goes To Stuttgart.
It begs the question - what is in store for Ireland fans this year? How about a song for the fans by the fans?
Diehard Ireland fans and talented musicians, Catalpa, have been together for almost five years and have recently aligned themselves to Irish soccer supporters, playing in venues around Lansdowne Road on match days.
Now the group have penned a Euro 2016 song called 'Irish To The Core' which they hope will "unite all Irish fans, north and south, on the road to France and beyond".
The group - who are made up of Ciaran Warfield, Stephen Collins, Raymond Donnelly and Phelim Warren - are long-time Ireland fans with one of their members the former manager of the Irish fans team.
Phelim Warren has been with the group for a little over a year and before that he managed the YouBoysInGreen.ie Irish fans team. The popular Irish fans website play matches on the same day as the senior team against fans from the opposing nations and under Warren won a Carling Nations Fans Cup and took notable scalps including England, Germany and Russia.
Commitments with Catalpa meant he had to hand over his match-day management duties as he swaps the shell suit for the squeeze box.
"I came on board a little over a year ago. I knew Ciaran (Warfield, son of the Wolfe Tones' Brian) and he asked me to come down when they were playing a gig for the Confederation Of Irish Soccer Supporters Clubs.
"Now we play before every match and it has been a brilliant experience. I do miss managing the YouBoysInGreen Ireland fans team. That was an amazing few years and it was an honour to represent your country and meet so many great people along the way. Maybe I will get the chance to do so again in the future."
That chance may be on the horizon for Warren.
With thousands of fans staying in the seaside town of La Rochelle about 90km from Bordeaux, YBIG have organised a match against the local team - an event that has blossomed into a festival that will no doubt encompass the whole town.
Catalpa will also be there as they are booked in to play two nights in General Humbert's Irish bar in the town while the Lord Mayor and, possibly, former French star and European Footballer of the Year in 1991 Jean Pierre Papin, will also be a part of what looks to be an unmissable few days for those who are staying in La Rochelle.
"YBIG.ie is a great community for events like these and when we were drawn to play in Bordeaux I got on to my friend Nicolas Bourdel who owns the General Humbert in La Rochelle," said Ireland fan Tommy Sheilds.
"The event and match, which will be played in a brilliant little stadium, has certainly gathered momentum. Every match YBIG play is a fundraiser for charity so I decided to put forward the charity for Carl O'Malley, the Irish Times journalist who sadly passed away last year.
"So we will raise money for the Carl O'Malley Children Education Trust and the chosen charity of Jean Pierre Papin. We are also working on getting a former Ireland player to get involved.
"Having Catalpa there will really add to the party atmosphere that we are expecting in La Rochelle."
