Easy to find, just opposite the park entrance.
The park is worth a walk around, it has a small but quite nice nature area at the opposite end to the cache, where the Pyl Brook has been diverted into the park, which attracts many insects and birds. There is also a little public footpath alongside the brook, next to the park.
Marked as terrain 1.5 due to the fact is probably not quite wheelchair accessible, would be a difficult reach.
And it's just next to a supermarket if you need to do your shopping too. And a fast food restaurant if you want to reward yourself with a burger.
