Have just spent the weekend in Brynich, Brecon. Highly recommend the site. Wardens are friendly, site is flat, toilet block is really clean. £18 per night (approx) well worth it if you like sites without single sex groups. Resturant on site a bit pricey but town centre not far away. 2 playgrounds for kids inc indoor play area. (£3.75 for 2 hours)
