There are lots of grey squirrels in the park, unfortunately they are an invasive species and have displaced the native red squirrels, but they are very cute. If you walk through the park in Autumn you will hear, lots of birdsong and the gentle thud of seeds falling from the trees.
The cache is a sneaky wee camo with only a log, bring a pen. You can reach it from the path, no climbing required. You may need tweezers.
