At a glance
A week in North Wales covers the region's key dimensions: Snowdonia mountains (Snowdon Railway, Zip World, Betws-y-Coed), the Anglesey coast (Beaumaris Castle, beaches), the castle towns (Conwy, Caernarfon), and the heritage railways (Ffestiniog, Welsh Highland). Book the Snowdon Mountain Railway and Zip World well in advance for summer visits. A car is recommended but a rail-based itinerary focused on the main corridor is possible.

Frequently asked questions
One week is an excellent duration for a North Wales holiday — it allows 2–3 days for Snowdonia activities (Snowdon, Zip World, heritage railways, waterfalls), 2 days for the coast and beaches (Anglesey or Llŷn Peninsula), and 1–2 days for the castle towns (Conwy, Caernarfon). You will not see everything in a week — the Llŷn Peninsula alone deserves several days, and the Clwydian Range and the Berwyn Hills are often missed entirely. But a week allows you to experience the region's major dimensions without rushing.
The best single base for a week in North Wales depends on priorities. Betws-y-Coed is the most central for Snowdonia activities and has the widest range of accommodation and restaurants in the mountain interior. Llandudno is the best coastal base — Victorian seafront, Great Orme, easy access to Conwy (8 miles) and Anglesey (20 miles). Llanberis is best if Snowdon is the priority — the Mountain Railway, the Llanberis Lake Railway and Llyn Padarn are all in the village (the National Slate Museum is closed for redevelopment until ~2027, and the former Electric Mountain visitor centre has closed). A self-catering cottage in the Conwy Valley or Nantgwynant gives the most flexible access to both mountain and coast.
Book the Snowdon Mountain Railway at least 2–3 weeks in advance for summer visits (June–August) and at least 1 week in advance for May and September. The railway sells out on popular summer dates weeks ahead. Book on the official Snowdon Mountain Railway website (snowdonrailway.co.uk) — avoid third-party booking agents. Specify the departure time — morning departures (9am–11am) are best for summit visibility before afternoon cloud builds. The return journey is included in the ticket; you can choose to walk down if you prefer. The summit journey takes 60 minutes; the summit is open for approximately 30 minutes before the train returns.
A car gives significantly more flexibility in North Wales, particularly for the Llŷn Peninsula, Harlech, and the smaller Snowdonia valleys. However, a good rail-and-bus itinerary is possible for those focused on the main tourist corridor. The North Wales Coast Line (Chester/Manchester/London to Bangor) gives access to Llandudno Junction, Conwy, Bangor, and Holyhead. The Conwy Valley Railway connects Llandudno Junction to Betws-y-Coed and Blaenau Ffestiniog. Sherpa'r Wyddfa buses (summer) connect Snowdon trailheads. For Anglesey: buses from Bangor. For Caernarfon: bus from Bangor (30 minutes). A car is effectively required for the Llŷn Peninsula western tip and Harlech.
Book in advance: Snowdon Mountain Railway (essential — 2+ weeks ahead for summer); Zip World (all venues — 1–2 weeks minimum for summer weekends); Llechwedd Bounce Below (1 week ahead minimum); Ffestiniog and Welsh Highland Railway (advance booking recommended); accommodation (self-catering cottages book up months ahead in summer — book as early as possible); Cadw Explorer Pass (can buy on arrival but check current pricing online). Day-visit attractions (Conwy Castle, Caernarfon Castle, Bodnant Garden) can usually be visited without pre-booking in shoulder season; summer weekend queues are possible at all castle sites.
Essential packing for North Wales: waterproof jacket and trousers (mountain weather changes rapidly; the coast is also wetter than the English average); walking boots or sturdy footwear for any mountain or hill walking; layers for cool evenings; a small rucksack for day walks; OS Explorer map OL17 (Snowdon) if walking in Snowdonia. For beach days: sun protection (UV levels can be high even in cloud), windbreak for beach use (often breezy), swimming gear. Optional: binoculars (wildlife, castle views, coastal birdwatching); a red torch if visiting dark sky sites; a wetsuit if wild swimming.
