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!!

At 2,408 feet (734 m), Craig Cwm Silyn is the highest point on the Nantlle Ridge. It rewards with glorious views back along the snaking ridgeline, backed by the mighty Snowdon massif. The ascent of its northeast ridge is an entertaining scramble, while Craig Yr Ogof – the mountain's north-facing cliffs – provide plenty of rock climbing interest.

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!

Craig Cwm Silyn at 734 m is the highest point of the Nantlle Ridge. It's a rocky ridge of a summit with good views along the ridge or down into the valleys on each side. Normally run as part of the ridge traverse, it makes a great day out in either direction.

Lovely views from the top, climb up isn't bad - can be slippery if its wet and in winter.
