The Isle of Anglesey – which has gained international press attention as the home of the Duke and Duchess of Cambridge – can lay claim to being the UK’s most royal island.

The “Kate and Wills” effect has seen the popularity of Anglesey as a tourist hotspot rocketing.

The couple have now returned to live on the island while Flight Lieutenant Wales continues his tour of duty as a search and rescue pilot with 22 Squadron, based at RAF Valley, and royal spotters have an excellent chance of seeing them enjoying life away from the media on the island.

Anglesey has royal connections dating back to the Tudors and the Plantagenet bad boy King John – not to mention the Welsh princes whose power base was on the island.

And the romance that the latest royal couple found on the island certainly rubbed off on when we spent a superb weekend based at the 19th century Tre-ysgawen Country House Hotel and Spa, at Capel Coch, near Llangefni.

Chief Executive Neil Rowlands believes Anglesey owes the royal couple a huge debt for generating “absolutely priceless” publicity.

He has named the bridal suite at the hotel the Cambridge Suite in their honour.

And guests at the family-run hotel can also use a specially prepared itinerary to visit places with royal connections on Anglesey.

Edward I built the last of his great castles at Beaumaris to dominate Anglesey, the traditional home of the Princes of Gwynedd whose own palace had been on the other side of the island at Aberffraw.

Just further down the coast near Cable Bay is Barclodiad y Gawres, the Neolithic burial place of a prehistoric king with its stunning views down the west coast towards the great sandy sweep of Llanddwyn, voted by the Sunday Times one of the ten best beaches in Europe.

On Llanddwyn Island is the tiny church of St Dwynwen, daughter of the 5th Century Celtic king and Wales’s patron saint of lovers, while another royal princess has her coffin in Beaumaris Parish Church.

Siwan – or Joan – was a daughter of the notorious King John and was married to Llywelyn the Great. Her empty stone coffin has a plaque over it explaining that it was moved from the Priory of Llanfaes on the North Wales coast and had been used for many years as a horse watering trough!

Also at Beaumaris is the Royal Anglesey Yacht Club which was granted its charter in 1885 by Queen Victoria who “danced the gallop” as a teenage visitor to the Marquess of Anglesey’s home at Plas Newydd, overlooking the Menai Strait.

William and Kate’s own part in the life of the island is also part of the itinerary – you can visit Trearddur Bay where they named the new lifeboat.

After a wonderful day in the sunshine at Trearddur and the even more stunning Roscolyn Cove – where the sand literally sparkles and where Wills is said to have enjoyed a pint at the local pub, we made our way to Tre-ysgawen.

Turning off the island road and on to the majestic driveway we entered a different world.

The gravel drive sweeps in front of the elegant country hall with its lawns stretching to its own woodland.

Walking into the grand entrance hall certainly has the “wow” factor. Tastefully restored by the family, the country house is elegant and has a real feel of walking on to the set of a period drama.

Yet it is certainly not too imposing, with friendly staff on hand to put you immediately at ease.

The “wow” factor continued as we were shown to our room – which turned out to be a stunning suite, complete with a four-poster bed, lounge area with huge bay windows, and a huge bathroom with a Jacuzzi bath built for two.

For a couple who spent their honeymoon in a low-budget hotel in Austria with a bathroom and loo down the corridor, this was more than we could have dreamed of for our 30th wedding anniversary treat.

We felt like royalty ourselves as we sat in grandeur on our posh sofa, enjoying a cup of Earl Grey and biscuits thanks to the in-room facilities.

There was time for a romantic walk in the woodland and gardens – taking a tour of the impressive walled kitchen garden full of wonderful vegetables and soft fruit, before we pampered ourselves before dinner.

Served in the grand dining room, after an aperitif in the panelled drawing room, dinner proved magnificent.

The culinary concept came about when the team working together at Tre-Ysgawen Hall decided they wanted to a unique and never-to-be-forgotten dining experience.

The menu changes regularly and the accent is firmly on seasonal, local and regional produce.

It was so local that the samphire, the tiny carrots and the raspberries had come from the hotel’s kitchen garden.

And what nicer after such a meal than to be able to choose to enjoy a whisky or brandy in the bar, or simply retire to your suite and a wonderfully comfy four-poster.

We woke early enough and feeling refreshed enough to make use of the hotel’s spa.

It is one of the obvious attractions of Tre-Ysgawen, with a large swimming pool, Jacuzzi steam room and sauna, as well as a gym and beauty treatment rooms.

It was great to be able to work up an appetite for the hotel’s popular breakfast, whether you chose a full Welsh or, like me, scrambled eggs and smoked salmon.

And there was just time for a wonderfully relaxing massage before we had to bid farewell to Tre-Ysgawen and enjoy an afternoon of exploring this lovely island.

If royal spotting doesn’t do it for you then what about Anglesey’s stunning natural beauty such as South Stack Lighthouse or Puffin Island.

There is the fascinating copper mining history, the fishing, or the chance to walk on deserted beaches.

Easy to reach from Shropshire and Mid Wales, either along the A55 or the A5 through Snowdonia, Anglesey is definitely somewhere we will be returning to.
