Extreme Halton — Bonus Mystery Cache

This is part of a series of caches celebrating the extreme points of Halton. This bonus cache is not at the given coordinates; instead, you can find its coords in the four other caches in the series.

Halton is a relatively small borough, mostly centred on the towns of Widnes and Runcorn, but also including the parishes of Hale, Halebank, Moore, Daresbury, Preston Brook and Sandymoor.

In this series, we visit Halton's extreme points! It will take you as far north, south, east and west as it's possible to get in the borough. In each cache you'll find part of the coordinates for this bonus cache.

Once you've been to Halton's extremities, you can now attempt to find this cache, which is in an extremely unexciting sort of place! You should be able to park right by GZ.

And just for fun, you might now want to finish off your extreme adventure by visiting Halton's highest and lowest caches: Halt on the hill near Halton Castle, and The Transporter Bridge II down by the Mersey.
