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!

Garn Boduan is an Iron Age hillfort and hill near Nefyn, on the Llŷn Peninsula in Wales. In a survey in the 1950s the traces of over 170 round houses were identified on this site, and around 100 round houses are still visible on the ground. Between 100 and 400 people may have lived in this fort. The lower stone rampart is the original defence built in the Iron Age. At a later date, perhaps in the 6th/7th century AD, a smaller rampart was built on the eastern side. It is also a UK listed Marilyn.

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.

The highest peak on the Nantlle Ridge, Craig Cwm Silyn is an excellent viewpoint for northern Snowdonia. The ascent of its rocky, northeast facing spur is an entertaining clamber, while to the west things broaden out towards Garnedd-goch. The mountain's north face, well seen from the village of Nantlle, is steep, rocky and popular with climbers.
