This cache is a 450ml clip-lock box hidden in one of the many small wooded areas along the Eastern side of the park. Enjoy the short stroll up a gentle grassy slope with open views back down across the park to the River Bollin.
There's a path into the trees that gets fairly muddy. Once you reach the wooden steps with a handrail, turn right off the path and you're in the right spot. The cache is out of sight of the houses and away from their back garden fences/hedges. The hint should make it easy to find the cache quickly, and the spoiler photo gives it away.
