Porth Tywyn Mawr Beach

Porth Tywyn Mawr beach translated means big sandy beach, and this is certainly true. This beach is quite remote and accessed down a back lane from the Valley to Cemaes road (A5025)

This beach is both long and wide and very flat, nearly half a mile in length. The beach is golden sand and is mainly backed by sand dunes.

This beach has a very rural feel to it, apart from the Penrhyn Bay caravan site at the southern end of it, there is very little else here.

If you look straight out to sea and slightly to the right you will be able to see the Skerries lighthouse, one of six lighthouses situated around the coast of Anglesey.
