After finding the last cache and then going through the gate, following the path, when you arrive at the junction follow the way marked signs, turning right, then left, crossing the wider track and continue downhill. This path could probably be a bit muddy and slippery at times.
At the waypoint follow the path signed to the left and then on reaching another gate, go through it and head to the cache and then the road at Luckdon, where you turn right.
