カーナーヴォンのおすすめホテル8選：ユネスコ城とスノードニア（2026年版）

Topping the list is the Celtic Royal Hotel, the only flagship 4-star in Caernarfon, sitting on Bangor Street right in the centre. A restored Victorian building with 110 rooms, it's also the single hotel in town with an indoor pool — plus a jacuzzi, sauna and steam room, the Castell Spa, and a gym that's open 24 hours for guests. The UNESCO Caernarfon Castle, built by Edward I in 1283, is an 8-minute walk down toward Castle Square. Rooms run from about $120 a night up past $300 for the bigger ones, which is high for a town this size, but you're paying for facilities nothing else here matches. It scores 8.6/10 on Booking.com and works best for families and couples who want the top standard in town.

The Anglesey Hotel sits on The Promenade on Caernarfon Harbour — the best spot in town for a water view, looking straight across the Menai Strait to Anglesey island. It is a 3-minute walk to Caernarfon Castle, the closest of any hotel on this list, with Castle Square five minutes further. The late-19th-century building keeps its old bones, and the ground-floor pub pulls in locals for real ale and Welsh beer. Rooms are tidy and classic rather than large, the front-facing ones being the ones guests fight over for that strait view. The restaurant downstairs runs Welsh dishes, and a full Welsh cooked breakfast is built into the rate. Doubles start around $91 a night, which is fair value given the location. The 8.7/10 score reflects what you are really paying for here — the setting and the harbour out front, not size or facilities.

The Black Boy Inn is the oldest inn in North Wales, open since 1522 — it turned 500 years old in 2022. It sits on Northgate Street inside the medieval town walls of Caernarfon, just a 2-minute walk from Caernarfon Castle. The building keeps its original bones — fireplaces, old oak beams, stone walls — and the ground-floor pub is the kind of Welsh local where townspeople settle in over a real ale. Rooms split into the original Old Wing and a later New Wing, and the restaurant serves Welsh plates in a genuinely historic room. The score is 8.8/10, the highest in this price band, and rooms start around $100 a night. It suits couples and anyone who likes a heritage boutique with real character.

Plas Dinas Country House is a 4-star heritage country house in Bontnewydd, about 5km from central Caernarfon. The 1620 manor was the family home of the Armstrong-Jones line for generations — the family of Lord Snowdon, husband of Princess Margaret — and sits on a 15-acre estate of garden, meadow and woodland. The Gunroom Restaurant serves Welsh fine dining built around produce from the estate, and the 9.2/10 Booking.com score is the highest in Caernarfon. Rooms start around $186 a night. It suits couples and anyone who wants a real Welsh country-house stay rather than a town hotel, with Caernarfon Castle a short drive away and Snowdonia closer than most in-town options.

Caer Menai Guesthouse is a 3-star B&B run by a Welsh family in a late-19th-century townhouse on Church Street, right in the middle of Caernarfon. It is a 5-minute walk to Caernarfon Castle, 3 minutes to Castle Square, and 8 minutes to the Welsh Highland Railway steam station, so you can leave the car and walk to everything. The highlight is the full Welsh cooked breakfast the owners make themselves — bacon and sausage from a Welsh butcher on Castle Square, fresh-baked Bara Brith, and cockle and laverbread on request. The seven rooms are simple and homely with en-suite showers, a tea and coffee tray, and fast Wi-Fi. At a 9.3/10 score and prices from about $80 a night, it is the best-value pick in the boutique bracket — best for couples and solo travelers who want the real thing over a chain.

Totters Independent Hostel is a backpacker hostel built into a 500-year-old building inside the Caernarfon town walls, right on High Street. Caernarfon Castle is a 2-minute walk away, and dorm beds start from about $26 a night. There's a common kitchen and a lounge with a proper Welsh-hostel feel, the kind of place travellers from all over end up swapping Snowdonia tips. It scores 8.9/10 on Booking.com, which is high for the hostel bracket and says a lot about the atmosphere and the welcome. If you're travelling on a tight budget or you actually want to meet people rather than hide in a private room, this is the obvious pick in town.

Victoria House Caernarfon is a boutique self-catering stay inside a Welsh-heritage townhouse on Church Street, right in the centre. Its 9.4/10 on Booking.com is the highest score in our Caernarfon list — the rooms are styled in a warm modern-Welsh look, and every one comes with a kitchenette so you can cook for yourself. It's a 4-minute walk to Caernarfon Castle, and Castle Square — with restaurants, pubs and the Green Bazaar — sits just 3 minutes away. Rooms start around $137 a night. The catch is that it runs without 24-hour staff and there's no breakfast, so you'll either cook or head out to a café. It suits couples and small families who want a stylish base they can settle into, with the family room sleeping four and a full kitchen of its own.

Bryn Eisteddfod Country House is a Welsh heritage manor in Glan Conwy, about 8km from central Caernarfon — roughly a 12-minute drive. The old house sits in a 5-acre country garden with the Snowdonia mountains in view, and the rooms are run as self-catering cottages that each sleep 4-6, so it works well for families or a group of friends who want their own space and a full kitchen. It scores 9.0/10, and the location is the real draw: Snowdonia National Park is only 8km away, closer than the in-town hotels by a good 5-7km, which makes it a strong base for hikers heading to Mount Snowdon. Rates start around $149 a night. If you want quiet Welsh countryside over castle-front convenience, this is the pick.
