Brave revellers take a dip as Hogmanay hailed a triumph
Annual Loony Dook follows spectacular 'best ever' Edinburgh street party.
More than 1,000 hardy souls have braved the icy Firth of Forth for the annual New Year's Day Loony Dook.
Some revellers wore fancy dress while others stuck to more traditional swimwear.
The charity challenge has been running for more than 30 years and is a celebrated part of Edinburgh's Hogmanay celebrations.
The sell-out event began with a parade along the town's High Street before plucky participants plunged into the water in the shadow of the Forth Bridges.
Those who took a daring dip in South Queensferry - where the water temperature was four degrees - were rewarded with a hot bowl of porridge.
Organisers praised the multi-national event which raised money for a variety of good causes.
In a joint statement, Charlie Wood and Ed Bartlam, directors of Underbelly, said: "What better way to clear those foggy heads from the night before than a swift dip in freezing cold water?
"Today, New Year's Day, we joined over 1,000 participants from 21 countries on the shores of South Queensferry to brave the waters of the Firth of Forth for the much-loved Loony Dook.
"We loved being 'Dookers' welcoming the New Year.
"It's terrific how much energy and excitement the Loony Dook generates and the fantastic fancy dress costumes people make and the money generated for charity."
Meanwhile, Underbelly also hailed the success of Edinburgh's street party which attracted 75,000 revellers.
As well as a spectacular fireworks display against the backdrop of Edinburgh Castle the highlights included a moving rendition of Auld Lang Syne by headline act Rag'n'Bone Man.
Mr Wood and Mr Bartlam said: "The day started with a storm and ended with a bang - without a doubt this was the best party ever.
"Our 9 minutes fireworks choreographed to Niteworks' and Dan Jones' score was truly spectacular and who will forget Rag'n'Bone man leading 75,000 in Auld Lang Syne?
"What a special way to ring in 2018.
"It's been spectacular and we'd like to thank all those who came and made the party such a great night for Edinburgh and Scotland."
Police Scotland confirmed there were no major incidents and only four arrests for minor disorder offences.
Chief Superintendent Kenny Macdonald, Divisional Commander for Edinburgh, said: "Edinburgh has once again shown why it's one of the greatest cities in the world, welcoming in the New Year in tremendous fashion.
"I would like to thank all of my officers and staff and the stewards for their outstanding work in helping us deliver another fantastic event."

Councillor Ian Campbell, Vice Convener of the Culture and Communities Committee at the City of Edinburgh Council, said: "Yet again, Edinburgh's Hogmanay celebrations have been the envy of cities across the globe.
"This was my first experience of Edinburgh's Hogmanay celebrations and they did not disappoint.
"It's true - Edinburgh really is the best place in the world to celebrate New Year."
