The cache requires a climb, and you'll probably have more success if you bring a strong friend along! If you look really hard, you can just about see the cache from ground level but if you can't spot it, you're just going to have to go up and look! There's a few likely suspects around GZ... are you game?!
The reserve is home to fowl which do wander around the whole forest, so if you bring a dog please make sure you have a lead in case it is required.
Once you have found the cache, you can continue your walk around to complete the loop which is a pleasant stroll of just over a mile in total with moderate gradients in places.
