The coordinates take you to a car park off the main Newport - Yarmouth road at Parkhurst Forest. Suitable for children, Parkhurst Forest has various trails and paths. There are nature walks with information boards along the way. A trails notice can be found on main path out of car park for more extensive walks. As you walk on the first trail keep eyes out for strips of pine kernels falling from tops of trees!

For a pleasant circular walk from the car park go to N 50 42.702 W 1 19.704, take the track North up to the Signal House and then approach clue 2 and then clue 1. Otherwise just go for it!
