I tried to visit this site two years ago with little success. I was in the area to look at the Walterstone Motte and Baily castle and thought while I was in the area I would check the hillfort out - as you do! I followed the narrow lane up to Grove Farm to ask for permission but was told the land belonged to a house on th eopposite side of the hillfort. I drove round to the house identified only to be told the land belonged to Grove Farm and I would have to ask there! In the end I gave up!!
