We've booked Trawsdir in Barmouth for the summer based on recommendations & great reviews.
The amenities are apparently spotless, there's a children's play area, the site not far from the beach & Barmouth is lovely to look around.
Fforest Fields, can't go wrong, lovely site, beautiful clean showers /toilets, lake to swim and boat in, ponds for the kids to go pond dipping and paddling. My favourite site in the UK.
I know a great site near Conway but it might be too far. Erw glas campsite. I went last year, toilets and showers are small but very clean and have heating.
Amazing family weekend with old steam engines, classic car displays, market stalls, and full catering and bar. And camping on site - Save £25 by booking in advance.
