Trearddur Bay

Trearddur Bay, located a couple of miles from Holyhead, is one of Anglesey’s best beaches. A vast expanse of sand overlooked by a large hotel and two golf courses, the beach is also the site of an ancient burial ground, excavated in 2003. This ancient link reflects how the town gets its name from the Welsh for “Arthur’s Town”.

The long curving sand slopes gently into the sea and gets the sun all day long. At low tide there is plenty of sand for walking and ball games. Trearddur Bay is perfect for watersports with sheltered conditions. Windsurfing, bodyboarding, dinghy sailing and kayaking are all popular activities as well as sunbathing, swimming and sandcastle building.

Behind the beach is a long promenade for strolling and enjoying coastal views along with a Lifeboat Station, established in 1967 and one of the newest on Anglesey.

What an amazing find

We were just wandering around Anglesey in the car when we came across this amazing beach.  It is lovely and sandy with children having fun building sandcastles and playing in the sea.. Perfect.

Great for families and young children, nice sand and shallow waters. Easy access to ice cream vans and places to eat.
Not good for dogs, unless small and able to stay on lead at all times.
