Porthdinllaen

Porthdinllaen is a small hamlet of only about two dozen buildings on the north coast of the Llŷn Peninsula in Gwynedd. The natural harbour is sheltered by a headland, and over 700 ships called there in 1861. A lifeboat house has stood here since 1864, and the village has belonged to the National Trust since 1994. At its centre is the Tŷ Coch Inn (Welsh for “Red House”).

Cars are not allowed down to the hamlet: only residents with a permit may drive in. You can park at the National Trust car park in Morfa Nefyn (postcode LL53 6DA) and walk from there along the beach or over the headland with the golf course, past an Iron Age hill fort. The National Trust circular walk is about 4 km long, moderately difficult with steep sections and steps, and takes one to two hours. From April to mid-September sand martins nest in the cliffs, and grey seals fish off the coast. Check the tides and the state of the path: according to the National Trust, the path between Porthdinllaen and the lifeboat house was last closed, with a diversion described (as of October 2026).
