Llanddwyn Island

Visiting Wales in January

January is a fantastic month for a romantic weekend. On 25th January, St Dwynwen, Wales’ patron saint of lovers, is celebrated. Dwynwen was a 4th-century princess who was prevented from marrying her beloved so prayed to God for help.  

She was granted three wishes, one being for true lovers to find happiness together. To show her gratitude, she became a nun and set up a convent on Llanddwyn Island on Anglesey.  

It’s a stunning place for a walk with sea views and the atmospheric ruins of St Dwynwen’s Church to admire. Cosying up for a ‘cwtch’ beside the fire of your cottage afterwards, is the perfect way to end the day.  

As a guide, the average temperature in Wales in January is 2 to 7°C.

In the Brecon Beacons, Welsh Mountain Ponies roam free in the secluded uplands, along with a thriving population of red kites. Visit for the scenery, the waterfall trails and the legends.

It’s summertime and the perfect excuse to head to the beach. From little coves backdropped by forests in Anglesey, to seemingly untouched shores of Pembrokeshire and Gower, Wales is blessed with many beautiful beaches. 

However, at the beginning of the summer school holidays, there’s nothing like grabbing the family for a holiday full of building sandcastles, paddling and trying water sports. Not forgetting ice-cream and fish and chips by the sea.
