As has been said, Treamble is a typical CC site.
Very well laid out and a choice of hardstandings or grass pitches.
Excellent dog walk on site with plenty more good dog walking near Perranporth.
The site has NO mobile phone signal on site, but it is available at the top of the hill on the roadway into the site.
Dont miss the entrance road to the site after leaving the main road or you WILL end up on a long circular route which is ONLY just wide enough for one vehicle, I know,,,,,done it, got the T shirt !
