Mountains, castles, lakes and the odd sheep traffic jam: Eryri (Snowdonia) has the lot. It’s one of the best trips you can take in a van, if you know the rules first. This Snowdonia campervan guide covers where you can legally sleep and how to dodge the parking stress at Yr Wyddfa. It also picks out the places worth the drive.
Snowdonia campervan rules: where you can sleep
Let’s get the boring bit done first, because it matters. The National Park Authority says staying overnight in a car park in a campervan isn’t permitted in Eryri. Camping on roadside verges or in lay-bys is out too. Wild camping isn’t allowed anywhere in the park without the landowner’s permission. Most of the land belongs to farms, forestry and other private owners.
So the plan is simple. Book an official campsite, and book early. The park says sites fill up fast between April and September. For the wider picture, read our guides to responsible overnight parking and whether you can sleep in your campervan.

Gwynedd’s Arosfan sites
Gwynedd Council runs four Arosfan sites, which work a bit like the aires you find in Europe. They’re at Y Glyn in Llanberis, Doc Fictoria in Caernarfon, Y Maes in Criccieth and Cei’r Gogledd in Pwllheli. At the time of writing a night costs £16.50, covering 4pm to 10am. You can stay two nights in a row at most, then you can’t come back for seven days. You can’t book, so it’s first come, first served. Park in the middle of your bay, which keeps a 6m gap between vans.
Facilities vary. Criccieth, Pwllheli and Llanberis have a point for emptying grey and chemical waste. Fresh water is available at Criccieth, Caernarfon and Pwllheli. Leave no trace, and take your rubbish with you if the bins are full.
Here’s the catch. They’re only for self-contained motorhomes with an on-board toilet and water, with no external containers. Chairs, tables, awnings and washing lines aren’t allowed, and nor is cooking outside. Plenty of VW campers won’t qualify, so check your setup honestly before you rock up.
Campsites that welcome vans
The National Park Authority lists campsites that suit vans. A few worth a look:
- Garth Farm, Capel Curig: tents and campervans only, vehicles under 6m, with views of the Snowdon Horseshoe.
- Llechrwd, Vale of Ffestiniog: vehicles under 8m. The site shuts for winter and reopens for Easter 2027.
- Cae Gwyn Farm, near Trawsfynydd: tents and small campervans, right by the Coed y Brenin trails. Ask first if your van is over 6m.
- Bennar, between Barmouth and Harlech: a short stroll from a sandy beach, and dog friendly.
- Dolgam, between Betws-y-Coed and Capel Curig: open all year, with a bus stop outside. No dogs or caravans.
- Tan-y-Fron, Dolgellau: open all year, with serviced hardstanding and up to two dogs.

Yr Wyddfa without the parking stress
Pen y Pass is the start of the Pyg and Miners’ tracks. Over the winter the car park runs as pay and display. The National Park says it goes back to pre-booking from Easter 2027. A standard space takes vehicles up to 5m long. Vehicles from 5m to 8m can only park by prior arrangement with the park, and anything over 8m won’t fit. Check your own van’s length before you go, rather than guessing. Drop-offs are allowed, so a friend with a car can save the day.
The easier option is the Sherpa’r Wyddfa bus. Park at Nant Peris and the bus takes about 15 minutes to Pen y Pass. From Llanberis it takes about 20 minutes. From Caernarfon it’s about 45 minutes. You get the views without the three-point turns.
Planning the Watkin Path instead? The park says the Nant Gwynant car park is often full by 7.30am. Take the S4 bus from Porthmadog to Pont Bethania, which takes about 35 minutes. At the time of writing, a day ticket for unlimited travel on all North Wales buses costs £7.50 for an adult. Remember that every route to the summit is a serious hike, even the ones people call easy.
Llanberis
Llanberis is the home of the Snowdon Mountain Railway. Its diesel service runs from 24 March to 31 October 2027. Check before you go, because mountain weather has the final say. It’s a brilliant shout if little legs won’t make the climb.
Just down the road, the National Slate Museum is free to visit. It tells the story of the quarries that shaped these valleys. In 2021, UNESCO named the area the Slate Landscape of Northwest Wales World Heritage Site. Perfect for a wet afternoon.
Castles: Caernarfon, Conwy and Harlech
Edward I’s castles at Caernarfon, Conwy, Harlech and Beaumaris make up a single UNESCO World Heritage Site. Cadw looks after all of them. Caernarfon is the showstopper, sitting on the River Seiont. Conwy comes with a walled town to explore. Harlech has perhaps the most dramatic setting of the lot.
From 1 November to 28 February, all three open from 10am to 4pm. Each has a pay and display car park, but Cadw says Harlech’s car park by the castle is small. Kids love the towers, and grown-ups love the views.
Beddgelert and Betws-y-Coed
Beddgelert is a pretty stone village with a famous legend about a dog called Gelert. It’s a great stop for a brew and a wander. The Lôn Gwyrfai path runs 4.5 miles from here to Rhyd Ddu. You can also go underground at the nearby Sygun Copper Mine, or catch the Welsh Highland Railway, which stops in the village. Just watch the Colwyn Banc car park, because it has a height barrier. A high-top or pop-up may not get in.
Betws-y-Coed is the other classic stop. Its Cae Llan car park is on the S1 Sherpa’r Wyddfa route. Leave the van there and ride to Pen y Pass in about 20 minutes.
Llyn Tegid (Bala)
Llyn Tegid is the largest natural lake in Wales, at 3.5 miles long. It’s ideal for paddleboarding, canoeing and windsurfing. You’ll need a National Park Authority permit to go on the water. Sort that before you inflate the board. Fishing needs a permit too.
Llŷn Peninsula
Head west for beaches and big skies. In 1957 part of the Llŷn Peninsula became an Area of Outstanding Natural Beauty. It’s one of only five in Wales. If your van is fully self-contained, the Criccieth and Pwllheli Arosfan sites are handy. Fancy more of Wales after that? Try our Pembrokeshire campervan guide.
Bottom line
A Snowdonia campervan trip is magic if you plan it. Book a proper campsite and keep car parks for daytime. Only use the Arosfan bays if your van is truly self-contained. Use the Sherpa’r Wyddfa bus for Yr Wyddfa, then fill the rest of your days with castles, lakes and slate. Check opening times before you set off, and pack a waterproof. This is Wales, after all.
