Traeth Lligwy is a sandy beach on Anglesey's east coast. It is approximately ¾ mile wide at low tide and backed by low dunes, with low cliffs of limestone and conglomerates to the southern side. There are two car parks, both with parking charges, although the more westerly of the two (reached by a lane from Brynrefail on the A5025) is not always attended and much more likely to have space during busy periods.
Facilities include a cafe, toilets, drinking water, cycle stands and a picnic table. Dogs are allowed at all times, and it's a popular beach for most watersports.
Just to the west of Traeth Lligwy is Porth Forllwyd (Grid Ref: SH503872), which is a small sand and shingle cove with a short harbour wall to one side. Unfortunately the land behind is private and the only way to reach this beach is along the rocky shore from Traeth Lligwy at low tide.
