The footpath alongside the boundary fence of Fort Halstead is quite oppressive with the high security fence on one side and a thick belt of trees on the other. There are only occasional views of the fields to the north to break the monotony. Frequent notice warn that Ministry of Defence guard dogs are loose on the other side of the fence and every now and again a projection in the wire fence, as here, allows security patrols to keep an eye on you.
