Aberffraw Bay (Traeth Mawr)

Aberffraw Bay (pronounced “Aber-frow”) is an unspoilt sandy beach that is just far enough from the nearest parking spot to make sure it never get busy.

Backed by extensive low sand dunes, the beach feels particularly expansive. These dunes are a Special Area of Conservation and lead all the way back to the village of Aberffraw where you will find shops, cafes etc

At the northern end of the beach the river Ffraw runs out to sea. This is apparently a good surf break on the right day, but that’s not too often!

Unsafe near rocks where the river is

Sep 01st 2020

No matter how safe you think this looks, do not go swimming near the mouth of the river or near the rocks on the side of the beach where the river flows into the sea. In a mild surf i saw 2 kids swept out in a riptide near there and their Dad went in with his kayak to save them but couldnt get back in. If the kids wouldnt have had life jackets on and someone hadnt noitced and gone in and dragged them out this would have gone really bad.

Beautiful beach but ruined by the amount of dogs allowed off their leash to run wild and as a result the amount of dog poo not picked up is disgusting. Today I saw more than one family with 2 dogs each freely allowing their dogs to foul the beach with no intention of cleaning up after their dogs, disgusting behaviour when you have children playing on the sands as well.

Unsafe tidal area and dog faeces on the common.

Jan 13th 2020

There are strong currents all around this area, particularly the rocky area at the mouth of the river Ffraw.  The river can be dangerous at high tides and sad events in the past unfortunately confirm this.  Please do not assume the flat beach means the sea is safe.

The area is a quiet traditional Welsh village and with respect can be enjoyed.  Unfortunately some people think it is okay to leave their rubbish, disturb the wildlife and not pick up dog faeces.  Be careful if you choose to walk in the dunes and on the common especially with children as there is dog mess around.  A recent walk across the common, through the dunes on to the beach had me avoiding dog poo, cows and the subsequent cow poo.

What did we get wrong?
