Things To Do In Caernarfon

Published on 2 Mar 2022 by Gwion Llwyd

Caernarfon is one of the must-see towns of North Wales. Home to the nation’s most magnificent fortress, a UNESCO World Heritage site and one of the best-preserved medieval castles on the planet, it is perfect for exploring on foot, with its 13th century walls, cobbled streets, and Georgian architecture. There are plenty of interesting shops, galleries, cafés and restaurants to discover too.

You can jump on board the Welsh Highland Railway from the centre of town for trips to Porthmadog, Rhyd Ddu, and Beddgelert. If you enjoy cycling or walking on your holidays, follow the traffic-free cycle track Lon Las Fenai, which is part of the Wales Coast Path. If you fancy heading slightly further afield, Anglesey is just a short hop across the Menai Bridge, around 10 miles north-east of Caernarfon. Or head to the Llŷn Peninsula, which begins around 10 miles south of Caernarfon. There are plenty of outdoor specialists in the area, and easy access to some of the region’s best adventure attractions.

Here’s a selection of our favourite things to do in Caernarfon.


Explore Caernarfon Castle

This magnificent fortress-palace on the banks of the River Seiont is grouped with Edward I’s other castles at Conwy, Beaumaris and Harlech as a UNESCO World Heritage Site. Edward and his military architect Master James of St George built the castle, the town walls and a quay all at the same time. The gigantic building project eventually took 47 years and cost a staggering £25,000. Over 700 years later, Caernarfon Castle is still Wales’s most famous – and arguably most mighty – medieval castle, recognised around the world as one of the greatest buildings of the Middle Ages. Its vast curtain walls, polygonal towers and turrets are inspired by the imperial Roman architecture of medieval Constantinople. It’s a hugely atmospheric place to explore and let your imagination roam. Don’t miss the Royal Welch Fusiliers Museum which is housed in two of the fortress’s towers.

Head to Caernarfon’s artist’s quarter at Cei Llechi

Once at the heart of Caernarfon’s thriving slate trade, Cei Llechi – which means ‘Slate Quay – has been recently redeveloped, and is now home to brilliant local artists, artisans, and craft makers. Cei Llechi also hosts regular events and markets.

Discover Caernarfon’s Roman roots

You can find out more about Caernarfon’s Roman roots at Segontium  – a Roman fort on the outskirts of Caernarfon. Established nearly two millennia ago, this strategically placed fort at the edge of the Roman Empire bustled with life for more than three hundred years. Thanks to excavated coins we know the Romans stayed until about AD394 – no other fort in Wales was held so long. Segontium not only controlled access to fertile and mineral-rich Anglesey but later helped defend the Welsh coast against Irish pirates. The Roman ruins are free to visit. Less than a mile from the centre of Caernarfon.

Take a ride on a steam train

This part of the world has no shortage of heritage railways, and one of our favourites, the Welsh Highland Railway, is based in Caernarfon. If ever there were a place to sit back and enjoy the nostalgic pleasure of steam, this is it.  Jump on board in the centre of town for trips to Beddgelert, Porthmadog and Rhyd Ddu, and enjoy the comfortable plush carriages, the nostalgic aroma of coal, and gentle chuff of the engine as it moves through spectacular mountain landscapes. A day out on this heritage railway is a magical way to explore the landscapes of North Wales.

Conquer Yr Wyddfa – Snowdon

It’s a bucket list favourite for anyone visiting North Wales – do you fancy climbing Wales’s highest summit  on your next trip here? Caernarfon is a short distance from the start point of one of the best routes up Yr Wyddfa – or Snowdon, the Rhyd Ddu Path (pronounced ‘rheed-thee’). This is one of the quieter ways up the great mountain, and offers some of the best views. Plan ahead by downloading the Snowdon Walks app, which covers the six main routes up, with detailed maps and a live progress tracker. You can read more about how to prepare for a walk up Snowdon, here. 10 miles from Caernarfon.

Master Moel Hebog

It’s Beddgelert’s own mountain: a worthy day of walking that will reward you with superb 360 views of Snowdon, Snowdonia and the North Wales coast. At 782m Moel Hebog is no lofty peak, but it shouldn’t be underestimated. A circular route covers around 9km and will take you the best part of a day. Make sure you check the weather, and that you will have enough light to finish, before you set off. You can read our guide to Moel Hebog, here. 12 miles from Caernarfon.

Climb Tryfan

Things To Do In Caernarfon

Where hiking meets proper mountaineering and an Everest connection. Tryfan is one of the great peaks of North Wales. This 917-metre granite peak is part of the rocky Glyderau range in Snowdonia, not too far from Capel Curig or Llanberis. Tryfan is a mountain where hiking meets mountaineering, and you will need a good level of fitness and some previous scrambling experience to take it on safely, but ropes are not necessary. All the same, be prepared for a significant level of challenge and dress appropriately: this is definitely no easy stroll. 17 miles from Caernarfon.

Climb Cnicht

Take on Cnicht – aka the Welsh Matterhorn – for breathtaking mountain scenery and one of Snowdonia’s best 360-degree summit panoramas. Cnicht’s pointed summit really stands out among the rounded bumps of the neighbouring peaks. It is part of Snowdonia’s Moelwyn range, a short drive from Porthmadog. Its appearance when viewed from Porthmadog has earned it the name the ‘Welsh Matterhorn’, albeit a somewhat smaller version (689m as opposed to a whopping 4,478m). You can read our guide to Cnicht, here. 20 miles from Caernarfon.

Other local walking ideas

For some more walking inspiration, you might be interested in these websites: Mud and Routes is a great information resource for walking in the area. Simply enter where you would like to walk and it will give you some tried and tested routes. Geocaching is popular in this neck of the woods and if you love a treasure hunt, then this is a great way to while away an afternoon, especially if you’re trying to keep the kids amused too.


Dinas Dinlle

Just a short drive from Caernarfon, Dinas Dinlle is a popular beach with easy access. Its upper shore of small pebbles soon gives way to a vast expanse of firm, golden sand. The sense of space is overwhelming – in good weather it’s possible to see all the way along the Llŷn Peninsula and across to Llanddwyn Island on Anglesey. The beach has two slipways, so it’s popular with watersports enthusiasts, especially jet skiers, power boaters, scuba divers and windsurfers. There is a craft exclusion zone and restrictions on dogs.

Explore Pen Llŷn’s secret beaches

Caernarfon sits just a few miles from the gateway to Pen Llŷn – the Llŷn Peninsula – an Area of Outstanding Natural Beauty and a real gem of the British Isles. One of the least explored parts of Wales, Pen Llŷn is the kind of place where you can take a picnic to a ‘secret’ cove or beach and feel like you have the whole place to yourself – because you probably will. Head to Pen Llŷn’s Porth Iago, Porth Or (Whistling Sands) and Porth Ysgo to enjoy some of the best ‘secret’ beaches’ in the UK. A pint on the sandy beach in front of the Ty Coch Inn at Porthdinllaen should be an obligatory part of any holiday to  Pen Llŷn. 

Head to Anglesey’s Newborough Beach and Warren

The forest is famed for its thriving red squirrel population and a huge raven roost. There are loads of trails and paths to explore, and the forest is a lovely place for a day out on foot or two wheels.

The welsh alphabet is phonetic so once you know how to say the letters, the theory is that reading the words is straightforward; you say what you see. A little time spent familiarising yourself with the alphabet will help no end when you’re trying to navigate your way around the area…

a short, as in ‘hat’, never as in ‘ball’
b as in ‘bag’. Although is there really any other way?
c always hard as in ‘cat’, never an s as in ‘precise’
ch like the ch in the Scottish word ‘loch’, but with more phlegm
d as in ‘dog’, never as in ‘djinn’
dd a buzzy ‘th’ sound, as in ‘this’. Think angry bees with a lisp
e short, as in pen
f v. This is very, very simple, and when you get really used to it, f will play hafock with your spelling
ff f. Equally, you can ffind yourselff getting too used to ff as well
g always hard as in ‘get’, never a ‘j’ sound as in the last g in garage
ng as in ‘song’, where the g isn’t hard, like in ‘gig’, but a soft glottal stop made in your throat
h as in hat, always sounded and never silent
as in ‘pin’
j accepted now because of the loan words from English that use it, like ‘garej’
l a ‘luh’ as in ‘lava’, but never an ‘ul’ sound as in ‘milk’
ll not as hard a sound to make as some would have you think. Raise your tongue to the top of your mouth as if you were going to say ‘el’, then make the ‘ell’ sound by blowing air round the sides of your raised tongue, instead of by using your voice. You should sound like an annoyed cat
m as in ‘mithridatize’. Or as in ‘mum’, if you want to be boring
n as in ‘nanobot’
o short as in ‘hot’, not round as in ‘hotel’
p can I have a p please Bob?
ph an English f, or Welsh ff sound, as in ‘phase’
r rolled. Some people just can’t get a rolled ‘r’ – their tongues are unable to vibrate in the right way. It’s a genetic thing, apparently,
similar to being able to roll your tongue into a tube, or turn the end upside down. Honestly, some people can, but my tongue’s not that prehensile. Roll if you can, don’t if you can’t
rh hr. Make a huffy, breathy sound before your rolled ‘r’
s always soft as in ‘sit’, never a ‘z’ sound as in ‘juxtapose’
t as in ‘top’. Can it get any simpler?
th as in ‘think’, softer and less buzzy than dd
u If you had stepped in something disgusting and made a kind of ‘eugh’ noise, the vowel ‘eu’ sound would about approximate
w oooooo
y ok, y breaks the rule that Welsh is phonetic. As a single syllable word, y is like ‘uh’, on the last syllable of a multisyllabic word it’ an‘u’ or ‘ee’, and anywhere else it’s like the unstressed, indeterminate noise of the final e in ‘garden’ or ‘letter’. Ysbyty (hospital) is the perfect example.
