The village of Trefor lies along the A499 between the towns of Caernarfon and Pwllheli and at the foot of the Eifl Mountains.
The small harbour was originally used to transport granite stones from the nearby mountain quarry. A number of small fishing boats occupy the inner harbour, and the pier which extends 200 meters to the sea is a very popular fishing spot.
