This is a sneaky wee camo-cache at the northern edge of Mugdock Wood. This will take you a little off the beaten path to a small glacial erratic in a more unexplored part of the park.
Note there is a main path that passes to the north of GZ, you CAN get to GZ from there, but you'll need to walk through long grass and normally boggy gound. To avoid the risk of ticks, and getting wet and muddy, follow the path from either E or W, heading in a southerly direction to get to GZ.
If you follow the suggested path, towards the east you come to a couple of small ponds - a nice spot to sit on the bench and have lunch.
At GZ, there is also the opportunity to pick up one of the clues for the Mugdock May-hem Mystery cache.
You may need tweezers to extract the log from this one.
