Nestled between the hills of northern Ll?n and the coast is the small town of Nefyn. The town backs it's own bay, with the small fishing hamlet of Porth Nefyn at it's western end (resembling it's neighbour, Porth Dinllaen).

The town itself has a few shops and cafes as well as a bank and a large hotel. Behind the town, Mynydd Nefyn is a small hilltop community overlooking the town to the north, towards Pwllheli and Llanbedrog to the south, and even to the Wicklow Mountains in Ireland on a clear day to the west.

Nefyn is centred around the crossroads between roads to Aberdaron, Pwllheli, Mynydd Nefyn and Llithfaen/Caernarfon. Pwllheli is approximately 7 miles away along the A497 which terminates in the centre of Nefyn.
