The pub is a little bit out of the way. But, it is well worth the effort. The Tŷ Coch Inn is nestled in the village of Porthdinllaen near Morfa Nefyn, Gwynedd on the north coast of the LLŷn Peninsula. With views across the Irish Sea towards Yr Eifl and a sandy beach on its doorstep, what better way to while away the hours? Access to the pub is via bicycle and foot as vehicular access is for residents only.

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 is a beautiful headland and the views onto the rocks and out to sea are super nice. Nearby too is Porthdinllaen lifeboat station which is always worth a visit and a donation.
