This section of the path highlights what the island is probably best known for – its sandy beaches. The path follows low rocky cliffs as far as the burial chamber of Barclodiad y Gawres at Cable Bay (Porth Trecastell). From here huge expanses of sandy beach backed by dunes stretch all the way to the Inland Sea, where you’ll join low lying farmland to Four Mile Bridge.

The walk starts at Aberffraw, skirts the estuary of the Afon Ffraw, before rounding the headland and following the coastline to Saint Cwyfan’s Bay and the wonderful “church in the sea” of the same name. Should the tide be on the ebb it is well worth making a detour and taking the causeway to the church, but don’t tarry too long as the incoming tide might well trap you on the island!

From Porth Cwyfan the path cuts inland for a short way before returning to the glorious coastline close by the ancient Burial Chamber of Barclodiad y Gawres. From here the path sticks to the coast, and the fine beaches of Llydan, Crigyll and Cymyran, all the way through to the inland sea, known as the Cymyran Strait.
