Depending on the day and time, the park can get quite busy,so some stealth may be required. The cache is far enough away from the viev of soccer fields that you should be fine though.
When there are no soccer related activities occuring the place tends to be empty. There's a small playground for children, and the occasional walker, but you can still be the only person in the entire park.
At the right time of year you can find some (non edible) fungi around the place, so why not have a wander?
