Cemaes Bay - Anglesey

If there is one beach I can remember from my childhood holidays in Anglesey it's Cemaes Bay. This is the kind of beach that has everything a small (or big) child could ever want. There's plenty of sand, and it's the kind that's perfect for sand castles. There are rock pools a plenty and even a promenade if you're too grown up for rock-pooling.

What Cemaes didn't have those many years ago was the St Patrick's Bell. Installed in 2014 this bell on legs is set to chime on the high tide.

There are actually two beaches at Cemaes; this one, Traeth Mawr which means "big beach", and another, Traeth Bach, just around from the harbour.
Both beaches are overlooked by the little town of Cemaes which has all the facilities you'll need for a day at the beach.
