Eryri rewards proper planning. The national park is large (823 square miles), the weather is highly variable, and the range of experiences on offer, from serious mountaineering to castle-hopping in the rain, means that the right preparation makes an enormous difference to your visit. This section covers everything you need to know before you arrive. If you are still deciding, read why Eryri makes a good UK holiday and our notes on planning your first holiday here.
When to Visit
Summer brings the longest days and the busiest paths; spring and autumn are quieter and often just as good on the hills; winter turns the high tops of Eryri (Snowdonia) into serious mountain terrain. Plan around the forecast rather than the calendar, though music festivals and live gigs are worth checking if you want your dates to coincide with one.
| Season | Best for | Watch out for |
|---|---|---|
| Spring (March-May) | Full waterfalls, valley walks, quieter summits | Lingering snow and ice on the high tops |
| Summer (June-August) | Yr Wyddfa, railways, lakes and beaches | Crowds, full car parks, late accommodation booking |
| Autumn (September-November) | Woodland colour, photography, quieter paths | Wet, windy spells and shorter days |
| Winter (December-February) | Castles, low-level walks, winter mountaineering for the experienced | Ice, very short days, reduced opening hours |
In winter conditions the paths up Yr Wyddfa (Snowdon) need an ice axe, crampons and the skills to use them. Without both, stick to the valleys.
Getting Here and Getting Around Without a Car
- Rail: the North Wales Coast line serves Bangor. The Conwy Valley line runs from Llandudno Junction to Blaenau Ffestiniog via Betws-y-Coed and Dolwyddelan, usually around six trains a day Monday to Saturday and fewer on Sundays. In the south, the Cambrian Coast line from Shrewsbury serves Tywyn, Barmouth and Harlech on its way to Pwllheli.
- Sherpa’r Wyddfa: buses link the start of every main Yr Wyddfa path: the S1 (Betws-y-Coed and Caernarfon to Llanberis and Pen-y-Pass), S2 (from Bangor), S3 (Caernarfon to the Snowdon Ranger and Rhyd Ddu paths), S4 (Porthmadog to Pen-y-Pass and the Watkin Path) and the S5 shuttle between Llanberis, Nant Peris and Pen-y-Pass. All use low-floor buses with a wheelchair space; check timetables on the Sherpa’r Wyddfa website or Traveline Cymru.
- TrawsCymru: the T2 runs Bangor to Aberystwyth via Caernarfon, the T10 links Bangor and Corwen via Capel Curig and Betws-y-Coed, and the electric T22 runs Blaenau Ffestiniog to Porthmadog and Caernarfon.
Parking and Pre-booking at Pen-y-Pass
Parking at Pen-y-Pass, the start of the Pyg and Miners’ tracks, must be pre-booked online through JustPark in the main season (in 2026 until 1 November). Expect around £25 for up to eight hours and around £45 for a full day; bookings cannot be extended. Drop-offs are allowed. Otherwise park at Nant Peris or Llanberis and take the Sherpa’r Wyddfa up. Regulars can buy an annual National Park parking permit (around £120) for car parks such as Capel Curig, Nant Peris and Ogwen, though not Pen-y-Pass.
Where to Base Yourself
Llanberis suits anyone focused on Yr Wyddfa. Betws-y-Coed has the railway, forest walks and plenty of places to eat. Beddgelert is on the Welsh Highland Railway near the Rhyd Ddu and Watkin paths. Capel Curig is the quiet choice for Ogwen and Moel Siabod. Dolgellau is the base for Cadair Idris, while Harlech and Barmouth mix coast and mountains. Our Where to Stay guide compares them.
Budgeting Tips
- Summit paths, lakes, waterfalls and forest trails are free: see our list of free things to do in Eryri.
- The Sherpa’r Wyddfa saves on parking and opens up point-to-point walks.
- Seeing several castles? Cadw membership or an Explorer pass beats paying at each gate.
- Self-catering and hostels stretch a budget; book early for school holidays and avoid bank holiday weekends.
Visiting Responsibly
Around 26,000 people live and farm in the park. Follow the Countryside Code: dogs on leads around livestock, gates left as you find them, litter taken home. Never park on verges or in passing places, and stay on the main path to limit erosion. A diolch (thank you) goes a long way. In an emergency on the hills, call 999, ask for Police, then Mountain Rescue.

Frequently Asked Questions
How many days do I need in Eryri?
Three or four days covers Yr Wyddfa, a lake walk, a railway and a castle, with a spare day for bad weather. A week lets you add the quieter south around Cadair Idris. Our suggested seven-day itinerary shows how it fits together.
Can I visit Eryri without a car?
Yes. Trains reach Bangor, Betws-y-Coed and the Cambrian coast, and Sherpa’r Wyddfa buses reach every main Yr Wyddfa path. Check timetables, especially outside summer.
Do I need to book parking at Pen-y-Pass?
In the main season, yes. Without a booking, park at Nant Peris or Llanberis and take the bus.
When is the best time to climb Yr Wyddfa?
May to September gives the longest days and the best chance of snow-free paths. Go early or midweek, and check the mountain forecast. Our Snowdon routes guide helps you choose a path.
