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.

This low headland juts out between Pwllheli and Criccieth on the Llŷn Peninsula. There's a trig point on top marking its summit at a modest 75 feet (23 m) but it's this proximity to the sea below that can make it quite dramatic, particularly when the waves are on the larger side. In clear weather, the views along the coast in both directions are stunning.

It’s a fact that proximity to the sea makes a peak feel higher. Yr Eifl has its ankles in Caernarfon Bay, and from its top Tremadog Bay on the other side of the Llyn Peninsula seems almost as close. As such, this modest mountain has a genuine loftiness, along with three summits and an Iron Age hill fort.
