I'd spent a week looking for a CL with hardstandings and serviced pitches. Someone suggested I try this site and they were able to meet all my requirement.
It is a newly established CL (writing this in Sept 2020) and has been formed by fencing off part of a field on a working dairy farm. All the pitches are huge in size with a hard standing area that is large enough for a caravan and car, or caravan and awning. Between each pitch, there is a massive grass area - probably the equivalent of 2 or 3 normal size pitches, so no feeling of being cramped here! We put the caravan n the hardstanding and the awning on the grass - no need for groundsheet or awning.
All the pitches are accessed from a gravel roadway and the grass is orders of magnitude nicer than my lawn at home.
Each pitch has a grey water drain, fresh water tap and mains hookup. Be aware that because of the size of the pitches, it is worth bringing a long hose to be sure of reaching the tap.
In addition, there is a small loo block - a domestic toilet pan that serves as an Elsan point, a single loo and a room containing a loo, washbasin and shower.
The location is remote, but not far away from many attractions. Bristol, Bath and the Cotswolds are all in easy distance. There is shopping in Tetbury or Malmesbury. Access is along narrow, single track roads, but there is almost no traffic (apart from tractors) and plenty of passing spaces. The instructions to find the site are 100% accurate and should be followed as access from other directions uses even narrower roads!
All in all, a wonderful CL and one that we will return to in the future. I suspect it will be very popular!
