Europe's biggest television screen is being erected in Limerick city centre for today's rugby match. The organisers estimate that up to 10,000 people may gather to watch the game.
There will be major road closures and parking restrictions in Limerick city centre from 7am today to facilitate the giant 45sq m outdoor television screen.
Organiser Fran O'Donnell of Futurama Productions said it was like transporting Thomond Park to the middle of O'Connell Street in Limerick.
People were planning to travel from across the country to watch the game in Limerick, he said.
"We have received a lot of phone calls from all over the country. People are travelling from Cavan, Meath, Dublin and Cork."
The free screening is sponsored by a number of Limerick businesses and organisations. Special arrangements have been made for viewers in wheelchairs.
Meanwhile, thousands of Munster supporters set off for Cardiff yesterday. A total of 14 chartered flights will depart from Shannon over a 24-hour period, carrying an estimated 4,000 fans, with hundreds more travelling on scheduled services, according to a spokeswoman for Aer Rianta.
"It will be the busiest weekend of the year because it's an onslaught of fans trying to get out of this area into Cardiff, Bristol and Birmingham, but we're prepared to handle it," said airport director Martin Moroney.
Some 3,000 fans left Cork airport yesterday and a further 3,000 plus have travelled over by ferry with the Swansea-Cork superferry over the past few days.
Some more intrepid travellers travelled by yacht. Experienced Cork sailors - Adrian Power, Pat Lyons, Brian Curtis, Kevin Horan and Tony Mahon - managed to make it across the Irish Sea in Adrian's 15m-long yacht Windhover, despite encountering some rough seas with occasional 12m-high waves.
Tony explained: "We decided to go beyond Roches Point on Thursday night to have a look and see what the sea was offering up and then we went on to Ballycotton so we could go straight across to Milford Haven this morning if everything was okay.
Yesterday was "Red Day" across Munster when many people wore red. Several hundred schools and workplaces signed up to the idea.
Munster fan Mick Cullinane from Cork headed to Cardiff yesterday with 29 friends for his stag party and the European Cup Final.
"I decided back in January to have my stag in Cardiff this weekend and I reckoned that if Munster were there, it would be a bonus," he said
