Boats at Llanfaglan Shore

Highlight • Natural

There's a little collection of boats here, pulled up from the beach behind with a backdrop of the Menai Strait. It's delightfully peaceful and a lovely place to pause for a snack. There are sometimes boats moored in the shallows as well, lolling around at different states of the tide.

View of Caernarfon Castle

Highlight • Historical Site

Castell Caernarfon is recognised around the world as one of the greatest buildings of the Middle Ages.

This fortress-palace on the banks of the River Seiont is grouped with Edward I’s other castles at Conwy, Beaumaris and Harlech as a World Heritage Site. But for sheer scale and architectural drama Caernarfon stands alone.

Here Edward and his military architect Master James of St George erected a castle, town walls and a quay all at the same time. This gigantic building project eventually took 47 years and cost a staggering £25,000.

The castle was born out of bitter war with Welsh princes. So of course its immense curtain walls and daunting King’s Gate were designed to withstand assault. But the polygonal towers, eagle statues and multi-coloured masonry sent a more subtle message.

Segontium Roman Fort

Highlight • Historical Site

Built by the Romans in AD 77 on the outskirts of Caernarfon, the Segontium Roman Fort was once the most important military base in North Wales. The Segontium was built on higher ground to better defend itself. Today, you can enjoy an interesting slice of history and views over the Menai Straits. The grounds are open from 10am - 4pm and entrance is free.
