RHYL scooped a silver prize in the Britain in Bloom competition.
MP for the Vale of Clwyd, Chris Ruane, said this is testament to all the hard work which has been put in to improving the environment over the past few years.
Rhyl picked up the award in the Large Town category at the Royal Horticultural Society (RHS) Britain in Bloom National Awards for 2012.
Mr Ruane, said: “This is absolutely wonderful news.
“I also have to pay tribute to the Rhyl in Bloom committee, which has worked tirelessly to get flowers and shrubs in place, litter picked and areas weeded.
“It has been a long hard slog over the past few years but seeing the results, it has been very worthwhile, and I believe that both the community and the environment has been enhanced by the work undertaken.
“I am very proud of this achievement and it will certainly help to improve people’s perception of Rhyl and put the town back on the national map.
Mr Ruane added that the town scored highly on the Brickfield Pond, and thanked Garry Davies at Denbighshire Country Services.
More than 1,200 communities, from big cities to small villages, took part and of these just 72 finalists were chosen for the UK Finals, with Rhyl representing Wales.
RHS Judge, Jeff Bates, said: “The North Wales town had the benefit of glorious weather for a whistlestop tour, involving a vintage Rolls Royce, open-top bus and the oldest miniature railway in Great Britain.”
White Rose Centre Manager, Richard Henderson, Mayor of Rhyl Councillor Bill Tasker, and John Dolan, responsible for the Horticultural side of things, travelled to Guernsey to represent to the town at the award ceremony.
RHS Britain in Bloom is the biggest voluntary campaign in the UK and works to improve people’s lives through community gardening.
