Hi MJR. I once visited a site in the Scottish Borders in a lovely place called Bellingham. Really enjoyed my time there. Quaint place, friendly site owner and it's within 5 mins, if that, of the village centre.
demesne farm campsite. Just Google it. Link I tried to put here won't connect after I tried it.
Not done the bunkhouses but the site is lovely. To get to your pitch, come off the high st and through the farmyard.
Give them a call if you are planning to be in that area?
