Snowdonia & the Llŷn Peninsula: A 5-Day Campervan Route from the Midlands

The short answer: two nights in the mountains, two nights on the coast. Drive the A5 in on day one, do your summit day from the Llanberis side on day two, then cross to the Llŷn Peninsula, which is what Cornwall was thirty years ago: fishing villages, beach pubs and single-track lanes that go nowhere except somewhere beautiful. Around three hours from Birmingham and worth every minute of it.

Day 1: the A5 into the mountains

Collect from 3pm and take the A5 the whole way: Shrewsbury, Llangollen, through the Vale and into Betws-y-Coed as the valley walls start to rise. It is one of Britain’s great road trips in its own right, built by Telford and easy in a camper. Allow 2 hours 45 with a leg stretch at Llangollen.

Stay at Llyn Gwynant if you can get in: a lakeside field under the flank of Yr Wyddfa (Snowdon) that might be the most beautifully situated campsite in Wales. Betws-y-Coed has good alternatives if it is full.

Day 2: the mountain day

A word of honesty about parking: Pen-y-Pass is effectively impossible for campervans, and the lay-bys fill by 7am. Do it the sensible way instead. Park at Nant Peris park and ride or in Llanberis, and either take the Sherpa’r Wyddfa bus to your chosen path or walk the Llanberis Path from the village.

If a summit is not the goal, you get most of the drama for a tenth of the effort at Llyn Idwal in the Ogwen Valley: a half-day circuit under Tryfan that feels properly alpine.

Finish in Beddgelert, all stone bridges and riverside benches, and one of the nicest villages in the park to eat in. Second night at Llyn Gwynant or a Beddgelert site.

Day 3: over to the Llŷn

A slow morning, then west. Stop at Criccieth for the castle and an ice cream on the front, then carry on to Morfa Nefyn. The walk out to Porthdinllaen is the point of the whole day: a fishing hamlet on a sandy hook of coast with the Tŷ Coch Inn sitting on the beach itself. Time it for low tide and walk back along the sand.

Head down towards Aberdaron for the night. The farm sites at this end of the peninsula are small, cheap and glorious: pick one with a sea view and watch the light go.

Day 4: the end of the land

Aberdaron is the last village before Bardsey Island, and it feels like it. Walk up Mynydd Mawr for the view across Bardsey Sound, then work back along the north coast to Porthor, better known as Whistling Sands, where the beach genuinely squeaks underfoot.

Afternoon options: Abersoch if you want shops and swimming, or Llanbedrog’s painted beach huts and headland if you want it quieter. Overnight around Porthmadog to set up the run home.

Day 5: Portmeirion and home

Portmeirion, the Italianate village on its own wooded estuary, is twenty minutes from Porthmadog and the perfect final morning: two hours of wandering somewhere that does not look like it can possibly be in Wales. Harlech Castle is the alternative, with the best castle view in the country.

Home is three hours down the A470 and A5. If your return is next morning, use the last evening for fish and chips in Porthmadog rather than rushing back.

The practical bits

Total driving: about 320 miles across the five days, front-loaded on days one and five.
Roads: the A5 and A470 are easy. On the Llŷn expect single-track lanes with passing places: go slowly, pull in early, wave. Our campers are under 2.1 metres wide and manage fine.
Parking: assume beach car parks take coaches and motorhomes unless signed otherwise; the National Trust ones at Porthdinllaen and Porthor are camper-friendly.
Overnighting: wild camping and overnight car park stays are not permitted in Wales. The farm sites are half the joy of the Llŷn anyway.
Phone signal: patchy at the far end of the peninsula. Download maps before day three.

Quick answers

Can I climb Snowdon without booking anything? The mountain is free, but parking is the constraint. Use Nant Peris park and ride or Llanberis and you do not need to book a thing. Just start early.

Is five days too long for Snowdonia alone? For most people, yes. That is exactly why this route splits it with the Llŷn: mountains lose their novelty around day three, beaches do not.

When should I go? May, June and September are the sweet spot: dry enough for the tops, quiet enough for the lanes, and campsite availability is far better than August.
