From Mormon rockers and banjo players to custard pie slingers and street performers.
The country was spoilt for choice over the weekend when it came to kicking back and enjoying the sunshine.
Mumford & Sons rounded off an ideal weekend of outdoor concerts in the Phoenix Park.
Newlyweds Jonathan and Laura Sexton carried on their marital celebrations at the banjo-loving rock gig last night with rugby mates Sean O'Brien, Rob Kearney and Jamie Heaslip.
The Killers headlined the park gig on Saturday night - which all went off without a hitch.
The band put on quite a show, with laser light shows, fireworks and confetti canons erupting.
The Killers don't just do stadium rock like U2; they play U2 as well. Singer Brandon Flowers and guitarist Dave Keuning delivered a ragged version of Pride.
Alongside originals Mr Brightside and Somebody Told Me, other tunes included Girls Aloud and Tiffany cover I Think We're Alone Now.
Meanwhile in Dublin's Merrion Square, the Street Performance World Championships were in full flight for the entire weekend.
Now in its eighth year, the festival has fast become one of the most popular events in Dublin's summer calendar.
DJ Ray D'Arcy got soaked in a mammoth water balloon fight along with over 1,000 competitors and there was a rainbow disco, stilt walkers, face painters for the entire family.
"Over 250,000 people will have seen some of the silliness by the end," organiser Shell Holden told the Herald.
"We were mixing custard in cement mixers to make sure every one could get gunged. And there were thousands of water balloons. It was frantic but a lot of fun."
The festival has become a firm favourite with families. "It's a fantastic day for the kids," Brendan Buck, of Wicklow said. "For all of us really."
Brendan was there with his six-year-old daughter Eanna. It's a great day for everyone."
"I love coming here," James Gibson (10) said. James had travelled up from Cork for the day with his mum Claire.
"It's lots of fun and we get to see our friends," James said. "I like the bean bags and the balloon man."
There was plenty to see; tattooed daredevil and contortionist Alkazam kept audiences transfixed, beatbox champ Bellatrix laid down the rhythm and Yukinko Akira threw paint at a canvas as he raved along to music.
"I've never been before but I'll definitely come again," Lyndsay Martin (28), from Blackrock, said. "There is so much going on – the tiniest man I have ever seen is over there dancing to techno music like a lunatic and painting. It's nuts but totally brilliant."
And while thousands flocked to the beaches, sailing enthusiasts descended on Dun Laoghaire for the 2013 Volvo Regatta on Saturday.
