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.

The three stones above Nant Gwytheryn (the Welsh language and heritage centre), perhaps representing the three peaks of Yr Eifl. From here a short detour to the centre can be made for a cake in the cafe.

These grand stones at the Yr Eifl car park are a memorial to the miners who quarried here in the 19th century. This area has a huge industrial history and it can be easy to get lost in the landscapes and forget the incredibly tough conditions these men worked in. The stones stand under the watchful gaze of Yr Eifl.
