Read the review by sandman and following their directions. Their was a gate stating private property but there was a gap at the side of the gate to get through.
The path was a dirt track used by the foresters. I followed the path through the forest until near the top where new trees were recently planted. The path ended here and for the rest of the way to the top I was following a path of lightly trampled grass. The ground is very uneven and there are thorny plants, so good shoes/thick trousers are recommended. I could only find the "top" of the hill because I had saved the co-ordinates on my GPS.
Overall a short walk (20-25 mins up), but the view at the top is worth it.
