Discover Porthdinllaen

Porthdinllaen, Llyn Peninsula, Wales

Porthdinllaen on the Llŷn Peninsula has an incredibly rich history. From the iron age fort on the headland to the grand idea of turning the harbour into the main port en route from London to Dublin at the turn of the 18th century, to the prolific shipbuilding and fishing industries which flourished during the 19th century. Many signs of this interesting past can still be discovered today.

Plenty to do

Porthdinllaen is a spectacular spot to enjoy a day on the coast with magnificent views, sheltered waters, fine sandy beaches, interesting rock pools, a chance to watch the comings and goings of local fishermen and the Ty Coch Inn on hand to provide refreshments.


Wildlife abounds here too. The soft cliffs are home to nesting sand martins and cormorants. Oystercatchers and other coastal birds can often be seen. The headland is also a popular spot with the local grey seals and one of the largest seagrass meadows in North Wales hides beneath the water providing a habitat for many different types of fish.
