In reply to Andypandyroo: Dol Gam - just before you come into Capel Curig on the A5. Really nice showers but no electric in the shower block. 5 minute stroll to the Tyn Y Coed, the best pub around that area in my opinion.
Otherwise the campsite opposite the Vanyol Arms in Nant Peris is fine. Stayed at both.
In reply to Andypandyroo:
The two opposite the vaynol are fairly poor standard and facilities but are in a good location and the one nearer llanberis is cheap.
> I always thought the Vaynol ones were pretty scummy.
Define Scummy? I stayed there numerous times while looking for houses in the area and I'd say it's the cheapest campsite in the area for the amenities provided.
In reply to Andypandyroo: Joe's farm on Ceunant Street/Capel Goch offers camping if you want good access to the village. It's a basic pitch up and go but only a ten minute walk into Llanberis. (follow the youth hostel signs from joe browns corner shop)
