The site of this hill fort is at the north end of Llŷn Peninsula about six miles to the south east of Caernarfon and some fourteen miles north of Pwllheli. The cliff above the coastal village of Dina Dinlle is called Boncan Dinas and is the site of the Iron Age hill fort. The banks of the fort can still be clearly seen although part of the site has been subject to coastal erosion.
