At the top of the very steep (walk don’t drive!) Bell Bank, just to the right of the large house in front of you, you’ll see a poo bin and steps up to the fields. As there are crops growing, there are never sheep or cows but there are often pheasants. The public footpath is very clear and after about 5 minutes, where Days Lane is off to the left, there is a parallel bridleway. Just before the farmhouse (Dovedale Farm) on the right, there is a public path going left through the fields, that goes up to Upton Wold, where the gardens are sometimes open to the public.
