North Wales castles road trip from Chester
From Chester: North Wales and Caernarfon Castle Tour
Duration: 10 hours
North Wales holds four of Edward I’s UNESCO World Heritage-listed “Iron Ring” castles - Conwy, Caernarfon, Beaumaris and Harlech - built in the 1280s to enforce English rule after the conquest of Wales. This 2-day road trip from Chester covers the three most accessible of them: Conwy and Caernarfon on the mainland, and Beaumaris across the Menai Strait on Anglesey, with enough time at each to actually explore rather than tick a box from the car park.
Why these three castles
Conwy, Caernarfon and Beaumaris each represent a different stage of Edward I’s castle-building programme and a different architectural approach - Conwy’s tight, linear design fitted to a rocky spur; Caernarfon’s deliberately imperial polygonal towers referencing Constantinople’s walls; and Beaumaris, the last and in some ways most technically advanced, a symmetrical concentric design built on flat ground with no natural defences to rely on. Seeing all three within a single trip makes the differences obvious in a way that reading about them separately doesn’t.
All three castles are recognised by UNESCO as part of the “Castles and Town Walls of King Edward in Gwynedd” World Heritage Site, alongside Harlech and Beaumaris (also included), reflecting how completely this ring of fortifications reshaped the region’s built landscape. What’s less obvious from a guidebook description is how differently each one feels to actually stand inside: Conwy is compact and dramatic, wedged onto a rocky spur with the estuary crashing beneath it; Caernarfon is vast and imperial, clearly designed to intimidate as much as defend; Beaumaris is almost serene by comparison, a textbook concentric design on flat land that never saw the military need it was built for. Doing all three in one trip turns a history-book abstraction - “Edward I’s Iron Ring” - into something you can feel the difference of underfoot.
Do you need a car?
Yes, for this particular route. Conwy is reachable by train via Llandudno, and Caernarfon has a bus connection from Bangor station, but Beaumaris on Anglesey has no rail link at all and is genuinely awkward without a car - the bus connections exist but add hours to the day. If you’d rather not drive, our Welsh castles in 2 days itinerary swaps Beaumaris for a more rail-friendly route, and a guided full-day tour from Chester covers Conwy and Caernarfon without you needing to drive at all.

Morning - drive to Conwy
The A55 expressway from Chester to Conwy takes about 55 minutes to an hour, running along the North Wales coast with sea views across Colwyn Bay before crossing the Conwy estuary into the town itself. Park near the town walls - Conwy has its own near-complete medieval circuit, smaller than Chester’s Roman walls but similarly walkable - and head to Conwy Castle. Entry typically runs £11-15 for an adult; the castle’s eight towers and complete curtain wall, built directly onto a rocky outcrop above the estuary, make it one of the best-preserved medieval fortresses in Britain. Allow 90 minutes to explore properly, more if you climb all the towers for the estuary views.
A private walking tour of Conwy’s medieval defences, run by a local guide, covers both the castle context and the town walls in 90 minutes to 2 hours if you’d rather have the history narrated than self-guided.
Check availability for the Conwy medieval walls walking tourConwy is also home to the smallest house in Great Britain on the quayside - a 5-minute detour and £1-2 entry if you’re curious - and Plas Mawr, one of the best-preserved Elizabethan townhouses in Britain, a short walk from the castle if you want to add another hour of history to the morning. The town’s suspension bridge, designed by Thomas Telford in 1826 to run alongside the castle, is worth a glance too - it was deliberately styled with castellated towers to match the medieval fortress it sits beside, a rare example of Georgian engineering trying to be architecturally polite to its 13th-century neighbour.
The A55 itself deserves a mention on this leg: it hugs the coastline for much of the drive from Chester, cutting through the Penmaenmawr headland via a tunnel and giving genuine sea views across Colwyn Bay in clear weather, making this one of the more scenic motorway-standard drives in Britain. Traffic can back up at the Conwy tunnel on summer weekends, so an earlier start than 9am is worth considering in July and August.
Midday - lunch in Conwy
Alfredo’s on Castle Street and the Bridge Café near the castle entrance both do a solid lunch (£8-14) with castle or estuary views.
Afternoon - Caernarfon Castle
The drive from Conwy to Caernarfon takes about 45-50 minutes, cutting inland past Bangor before reaching the Menai Strait. Caernarfon Castle is the grandest of the Edward I castles, built as a deliberate statement of royal and imperial power, with polygonal towers modelled on the Theodosian Walls of Constantinople - a design choice unique among British castles and one of the clearest signals of how seriously Edward I took the symbolism of conquest. It’s also where the investiture of the Prince of Wales has traditionally taken place in the modern era. Entry runs roughly £11-16 for an adult; allow at least 90 minutes, and walk the free town walls circuit around Caernarfon itself for views over the Menai Strait towards Anglesey.
Caernarfon’s town walls, unlike Conwy’s, were built as a single integrated project with the castle rather than a separate later addition, and the whole walled circuit - castle, town walls and the harbour gate - was designed to control the strategically vital Menai Strait crossing point to Anglesey, which is exactly where day two of this itinerary heads next.
Evening - overnight in Caernarfon or Bangor
Staying in Caernarfon itself puts you closest to Anglesey for day two - the town has a reasonable choice of guesthouses and B&Bs in the £70-110/night range, with a handful of decent restaurants around the castle square. Bangor, 20 minutes away, offers a wider choice of accommodation if Caernarfon’s options are full.
Day 2: Anglesey and Beaumaris Castle
Morning - cross the Menai Strait
From Caernarfon or Bangor, cross onto Anglesey via the Britannia Bridge (about 15-20 minutes from Bangor) and head to Beaumaris, a small, elegant harbour town. Beaumaris Castle is widely considered the most technically sophisticated of Edward I’s Welsh castles despite never being fully completed - its concentric “walls within walls” design, built on flat marshland with a moat and its own tidal dock, represents the peak of medieval castle engineering. Entry typically runs £9-13 for an adult; allow about an hour, since the site, while architecturally significant, is more compact than Conwy or Caernarfon.
If you’d rather have a guide cover Anglesey’s wider history alongside the castle, a full-day tour taking in Beaumaris and the island’s ancient sites runs from Bangor or nearby.
Check availability for the Anglesey full-day tour with lunchMidday - lunch in Beaumaris
The Bulkeley Hotel and several harbourfront cafés in Beaumaris do lunch with views over the Menai Strait towards Snowdonia’s mountains on a clear day - a striking backdrop that most visitors don’t expect from what is, on paper, just an island detour. Beaumaris itself is a genuinely handsome small town beyond the castle, with a Georgian courthouse and Victorian gaol both open to visitors if you want to extend the stop into the early afternoon, and a working harbour that still launches small fishing boats out into the strait.
Afternoon - the drive back to Chester
The return drive from Beaumaris to Chester takes around 1 hour 45 minutes to 2 hours via the A55, depending on traffic through the Conwy tunnel, which can back up on summer weekends. Build in a buffer if you have onward travel plans for the evening.
Budget for two days
- Accommodation (1 night, Caernarfon/Bangor area): £70-130 for the room
- Car hire (2 days, economy) if not using your own: £50-90
- Fuel for the full loop: roughly £35-50
- Conwy Castle entry: £11-15
- Caernarfon Castle entry: £11-16
- Beaumaris Castle entry: £9-13
- Meals across 2 days: £50-80 per person
- Total per person over 2 days (sharing a car for two): roughly £150-230
The three castle entries together (£31-44 per adult) are the only truly fixed cost here beyond accommodation and fuel - everything else, from the coastal drive itself to the town walls circuits at Conwy and Caernarfon, costs nothing beyond time. If you’re travelling as a couple sharing a hire car and a room, the per-person figure above is realistic for a comfortable but not extravagant trip; solo travellers should expect the car hire and fuel costs to weigh proportionally heavier on the total.
Packing and driving notes
North Wales’s coastal roads are generally in good condition, but expect single-carriageway stretches and slower-moving agricultural or tourist traffic once you leave the A55 for any of the town centres, so budget more time than a satnav estimate suggests, particularly in summer. Bring waterproofs regardless of season; all three castles are largely open to the elements once inside, and towers and battlements offer little shelter from sudden coastal squalls, which are common even on otherwise clear days. Sturdy, grippy footwear matters for the tower stairs at Conwy and Caernarfon, which are original medieval stone in places and can be uneven and slippery when wet.
Tourist traps to skip
Avoid parking directly outside any of the three castle gates in peak summer - all three towns have cheaper car parks a 5-10 minute walk away, and the premium spots near the entrances fill first regardless of price. In Caernarfon, some souvenir shops near the castle entrance charge noticeably more than shops a street or two back into the town centre.
If you have more (or less) time
If two days feels rushed and you’d rather add Snowdonia’s mountains alongside the castles, our Chester and North Wales in 3 days itinerary extends this same route with a day in Eryri. For a version that swaps Beaumaris for a rail-friendlier route without your own car, see Welsh castles in 2 days.
Frequently asked questions about the North Wales castles road trip
Which of these three castles is the most impressive?
Caernarfon is the grandest and most historically significant, but Conwy’s completeness and dramatic setting on the estuary make it many visitors’ favourite to actually walk around. Beaumaris is smaller but architecturally the most sophisticated design of the three.
Do I need to book castle tickets in advance?
Not usually - all three sell tickets on the day, and queues are rarely long outside peak summer weekends. Booking ahead mainly saves a small amount of time rather than money.
Is this itinerary doable without a car?
Not comfortably for the Beaumaris leg, since Anglesey has limited public transport. Conwy and Caernarfon alone are reachable by train and bus; see Welsh castles in 2 days for a car-free alternative that drops Beaumaris.
What’s the best time of year for a North Wales castles trip?
May to September for the longest daylight and driest conditions, though all three castles are open year-round with reduced winter hours. Clear days give the best views from Beaumaris across to Snowdonia, so checking the forecast before committing to the Anglesey leg is worth it if photography matters to you.
How much walking is involved at each castle?
Conwy and Caernarfon both involve tower climbs on narrow spiral stairs if you want the best views - not ideal for limited mobility, though ground-level access covers the main courtyards at all three. Beaumaris is the flattest and most accessible of the three.
Can I add Harlech Castle to this trip?
Harlech is further south, roughly an hour beyond Caernarfon, and would need a third day or a significant reroute to include comfortably - it’s a better fit for a longer North Wales trip or a separate visit than an add-on to this particular two-day loop.
Is Anglesey worth the extra day just for Beaumaris Castle?
Beaumaris alone is a relatively short visit, but the island has enough else nearby - the South Stack lighthouse, Holyhead’s Roman fort remains, and genuinely striking coastal scenery - that most visitors find the detour worthwhile beyond the castle itself, particularly if you have a spare afternoon rather than needing to head straight back to Chester.
Should I book a guided tour instead of driving myself?
If navigating unfamiliar roads or narrow historic town centres isn’t something you enjoy, a guided day tour from Chester covering Conwy and Caernarfon removes that entirely, though it won’t reach Beaumaris on Anglesey, which sits outside most standard day-tour routes from Chester.
