An old creek crossing from back in the day before the city council did a bit of commumity develpoment along the creek, the path run's for a couple of km's along Russell's Creek and is a popular walking & riding path with a section designated for dog's off leash, the path is also use by the local's to commute to school, town, etc, I would not recomend riding a bike across the bridge (the kids wheels have fallen down the gaps) but it is quiet safe to walk across if you happen to park at the tennis courts located just south and a tad west of GZ. This path is popular so be on the look out for muggles. You do not have to cross the creek commando style but you can if you want to, the cache is an eclpies mint tin painted black and it only has a log so bring your own pen.
