HH Mystery Cache

The cache is not at the coordinates above, which are for the entrance to Vicar Water Country Park. If arriving by car, this is the entrance to head for. Then, drive on for another half mile or so to the car park. Note that the barriers will close at 8 p.m. From here, you can walk or cycle along superb paths to the cache area.

The cache is actually at N53°09.ABC,W 001°06.DEF, where ABCDEF is a six-digit number.

From the car park, head past the picnic area and along the good path towards the National Cycle Network sign (see Additional Waypoints). From there: you're on your own! You'll need to deduce the final coordinates before you leave home.

The container is a camouflaged box and has enough room for a few small swaps and trackables. You should find it perched about three feet up a tree.
