You should see a Public Right of Way ahead of you, going diagonally across the field, under the power lines, to the far corner.

But, again, you may have to divert clockwise around two sides of the field. If so, go to your left down the inside of the field boundary, heading roughly south-west along the top of Sydney's Wood.

When you get to the corner of the field, at the NW coner of Sydneys Wood, turn right and head roughly north-west to the next corner of the field. You will see the electricity cables running right to left ahead of you.
