Llanaelhaearn is nestled at the foot of Yr Eifl to the north west and the Gyrn Hills to the north east, on the A499 as it cuts across the peninsula from Pwllheli on the south to Trefor on the north coast.

The B4417 runs out of the village to the west, along the southern slopes of Yr Eifl towards Llithfaen and Nefyn. The village has a small church, sub post office, cafe as well as a bakery.
