Sometimes known as Moelfre North Beach, Porth yr Ynys (above) is a beach of shingle near Moelfre on Anglesey's east coast. It looks out towards the island of Ynys Moelfre, about 100 yards offshore. The coastal path runs along the back of the beach.
A little further west is Porth Helaeth (Grid Ref: SH511868), which is almost entirely rocks and pebbles. Access is from the coastal path which drops down to beach level. On the top of the hill to the west is a memorial to the Royal Charter - an iron-hulled steam clipper travelling from Australia to Liverpool, which was wrecked on the rocks in hurricane force winds during the Great Storm of October 25/26th 1859.
The names Porth yr Ynys and Porth Helaeth translate as 'Island Cove' and 'Wide Cove'.
