I think Hilfield Hill is a hidden treasure. My expectations, based on preliminary research, were not great but I had a lovely couple of hours there and would happily recommend it to any one. Not a lot of exotic nature to be seen perhaps with no rare species on offer but a nice walk and lots to see in the way of flowers and insects. It is an area of grassland surrounded by mature broadleaved woodland which means there is a lot of 'woodland edge' scrub habitat which is always interesting. Well worth scouring the brambles, nettles, thistles and hogweed for butterflies, hoverflies and beetles.
Hilflied is easy walking and not a large site so if you are still pretty mobile and are looking for something else to make the trip worthwhile why not tie it in with a visit to the neighbouring Dorset Wildlife Trust reserve at Hendover Coppice?
