The cache is a small-medium sized camoflouged container located in the woodland just off the beaten path. There are two picnic tables, if you walk clockwise around the park and woodland, you'll come to the first picnic table (see reference point) which is a good marker for you, as GPS coverage will be poor near GZ. The picnic table is 30m due north of GZ. 
You can park in the Park's Car Park, but be aware of the very narrow bridge that is difficult to drive larger vehicles across. The park features a great childrens playground, community pitch, adult gym and a short woodland walk.
