Well worth the detour to visit the harbour and beach. Be sure to choose your route out of Trefor carefully. There is a very challenging hill if you are up for the challenge!!

Tre'r Ceiri is a truly spectacular hillfort dating back to the Iron Age. In English the name means 'town of the giants.' A giant of a hillfort it is too and one of the best preserved of all with stunning views across the Llŷn Peninsula. The settlement is surrounded by stone walls that are amazingly largely intact. Some of these walls are four metres high in places. Inside the fort are the remains of around 150 houses which in days gone by would have had turfed roofs. A truly amazing place to visit!

Set at the foot of fishing village, Trefor, is a lovely little bay that has clear water and a mountainous backdrop.

Trefor is a Welsh village occupying a stunning spot. It sits between the sea and several large, craggy hills, providing an incredible backdrop no matter which way you look. To get the best views of its location, head out to its pier, which sees sweet little fishing boats in the foreground of the mountain-like hills.

The coast path here offers dramatic views up to the Yr Eifl quarry, now long abandoned. You can still see the workings clearly, with imposing buildings seemingly carved into the rock itself. In the foreground sit a couple of former quarry houses, now holiday cottages. Painted white, they almost seem to glow against the grass and rock around them.
