I know of a couple.
One in chobham. It has a 20x40 ring and grazing, and an american style barn. It has a website : http://www.willowviewfarm.co.uk/
But I'm not sure about the prices
ps: the first yard (chobham)was excellent for taking me out to loads of xc and sj schooling, so it's really good if you want to get a lot of experience because they seem to know some top riding people and all the venues around surrey.
No, had a bit of a falling out with the head yard girl person, and decided we wanted somewhere a bit more competiton-orientated because no one seemed to do any competing there.
The yard I moved to is sooo much better
Loads of people compete there.
Is your 4th pic @ tweseldown?
