The county has long been known as the “Garden of England, but taking into account its new attractions, such as the Turner Contemporary Art Gallery, and established favourites such Canterbury Cathedral and its numerous beaches, it is perhaps not so surprising that it pushed Kerry in the Republic of Ireland and the Black Forest, in Germany, into second and third spot respectively.

Sandra Matthews-March, the chief executive of Visit Kent, said she was absolutely delighted at the accolade.

I’m thrilled, but not really surprised, she said. Kent has undergone something of a renaissance over the past 10 years and lots of wonderful new family-friendly attractions have opened up.

One old family favourite finally re-opens its doors next week after a £30m regeneration scheme reached completion. The reimagined Dreamland Margate, designed by Wayne Hemingway, is the culmination of an 11-year project to save the oldest surviving amusement park in the country and make a huge addition to Kent’s tourism portfolio.

Ms Matthews-March said the county was also getting recognition for its “white sandy beaches” which were now on a par with the county’s numerous gardens.

“We’ve been known for so long as the ‘Garden of England’, and that’s an important brand to have, but we now have the most amount of blue flag beaches in the UK, so people are coming here now not just for the countryside but also the sun and sand too.

“There has been a huge concerted effort between public authorities and private companies to keep a lot of these attractions alive. To get this wonderful accolade from someone like Lonely Planet is an added bonus, just fantastic.”

It was also no surprise, therefore, that new Tourism Minister Tracey Crouch made the county the destination for her first official appearance earlier this month.

The Chatham and Aylesford MP cited the local “world class” attractions as the reason why international visitors spent a record £21.8bn in local economies last year.

Two other UK destinations – the island of Skomer off Wales’s Pembrokeshire coast and the nearby Marloes Sands – made the 10-strong family holiday list.

The Lonely Planet experts said Kent was seen as being “full of opportunities for time travel to intrigue curious young minds”.

Singled out were the resort of Broadstairs, once home to Charles Dickens, the White Cliffs of Dover, and the seaside town of Margate, which has become “gentrified without losing its personality”.

Kerry, meanwhile, was described as a destination which “appeals to the imagination of travellers of all ages”.

Lonely Planet also compiled a list of the 10 best beaches in Europe, with two UK beaches making it into the list: Bantham Beach near Kingsbridge, in Devon, in sixth place, and Scotland’s remote Sandwood Bay in Sutherland one place further back, “where the views more than make up for the cold sea water”.

Leeds Castle

Billed as “the loveliest castle in the world”, with 500 acres of parkland and gardens to complement the building with its surrounding moat.

The gallery is free, the amusement park costs just under £56 for a family of four.

Broadstairs

The coastal town in Thanet is “brim-full of nostalgic, old-world seaside charm” and was Charles Dickens’s favourite holiday spot.
