Camping in Snowdonia (2026 guide)
Yr Wyddfa, the Carneddau ridges and a coastline that keeps surprising people who only came for the mountains. Here's where to pitch, when to go, and how to book ahead of the crowds.
Snowdonia — Eryri, to give the national park its Welsh name — is the busiest stretch of mountain country in Wales, and for good reason. Yr Wyddfa (Snowdon) draws the crowds, but the park is much bigger than one summit: the Carneddau to the north are among the wildest, least-visited hills in the country, and the coastline from Barmouth up to Conwy adds beaches and estuaries most first-time visitors don't expect.
Where to pitch
Betws-y-Coed is the classic base — a village built around walkers and climbers, with campsites in the Conwy and Llugwy valleys putting you close to the Gwydir Forest and the Ogwen Valley beyond. For Yr Wyddfa itself, sites around Llanberis and Nant Peris sit at the foot of the main paths (Llanberis Path, Pyg Track, Miner's Track) without the drive most other bases require. If you want quieter ground, the Carneddau side around Rowen and Abergwyngregyn has smaller, farm-based sites with a fraction of the visitor numbers and views that are arguably better.
Don't overlook the coast. Campsites around Harlech and Barmouth give you a genuine choice each morning — mountains or beach — and tend to be less booked-up in summer than the honeypot valleys inland.
When to go
May and June are the sweet spot: long days, the bracken hasn't taken over the lower slopes yet, and the main routes up Yr Wyddfa are markedly quieter than July and August. September brings a second good window — settled weather odds are still decent and the summer crowds have thinned. Winter camping in Snowdonia is for the experienced only; conditions on the higher ground turn genuinely alpine with very little warning.
Getting the pitch you want
Snowdonia campsites near Llanberis and Betws-y-Coed book out weeks ahead for July and August weekends — the same pattern as the Lake District and Peak District, just with a shorter season either side. Midweek availability is far better, and the Carneddau-side sites rarely sell out at all, which is one more reason to camp there if flexibility matters more than proximity to the main summit paths.
Beyond the summit
The Carneddau ridge — Wales' largest continuous area of high ground — has none of Yr Wyddfa's crowds and some of its best views, including wild ponies that have grazed the tops for centuries. The Ogwen Valley, sitting between the two ranges, is the park's best single base for shorter walks: Tryfan, Cwm Idwal and the Glyderau are all within a morning's reach. Coastal options around the Llŷn Peninsula, just west of the park boundary, are worth the extra drive for quieter beaches and some of Wales' best surfing.
