This Location Does Not Fail

Porthdinllaen, is a small coastal village in the Dwyfor locality on the Llŷn Peninsula within Gwynedd, Wales, located on a small promontory, and historically in Caernarfonshire. It is near the larger village of Morfa Nefyn.
Porthdinllaen was originally a fishing port, based around a natural harbour at the west end of a bay over a mile and a quarter (2 km) across, and with over one hundred acres (40 hectares) of safe anchorage. The harbour is sheltered by a headland jutting out to the north from all but a north-easterly wind, and as the only such haven on the Llŷn Peninsula, it has been used for many centuries of trading, and as a place to run to for shelter in a storm.
