Segontium Romon Fort is an impressive excavated fortification located just outside Caernarfon. It was founded by Agricola in AD77, and it was garrisoned for over three hundred years. It was the longest-held Roman fort in Wales and used to hold a 'cohors milliaria,' a regiment of about 1,000 auxiliary infantry, mainly recruited from Belgium and Germany. It was linked by Roman roads to the main legionary bases at Chester and Caerleon by a series of marching camps and other forts.

This stunning mile long sandy beach is at the far end of the Llŷn Peninsula. Its beauty is that it is so close to Aberdaron itself, where there are good places to eat, shops, and car parking. This beach offers breathtaking views out into Cardigan Bay and provides a charming, beautiful atmosphere that is truly magnificent.

Aberdaron is a very beautiful but busy coastal village that has an ancient pedigree. In days gone by this fishing village used to be the last stop for pilgrims on the way to nearby Ynys Enlli, or Bardsey Island. Now it is a quaint but vibrant tourist hub. There's plenty to do at Aberdaron, the surrounding headland has miles of sandy beaches and secret coves to explore. There is also hiking galore as the Wales Coastal Path passes through here and being out on a headland there are a myriad of other hikes. Also let's not forget the one mile long sandy beach here which is one of the finest in Wales.
