This is a night trail, so you will need to bring your torch or headlamp, and find it at night. It will be near impossible during the day.
Park at the given coordinates, there is a large carpark, which will be free in the evening.
Look for the main entrance to "Tiffen Park" and start shining your torch from here. you will soon spot a trail of Silver Reflectors (Fire Tacks), which you will need to follow. Some of the fire tacks are high up on trees, so make sure you give your torch a good shine around.
Half way along the first piece of track, you will come across two fire tacks together. This indicates there is a trading container near by which you can search for. This container does not contain a log book, and is not an official part of the geocache, it is just an added extra to keep kids interested.
Continue to follow the path until you see Three Fire Tacks on the same tree, at this stage you need to leave the path, and look for a further Two fire tacks together. This final pair of Fire Tacks indicates where the final cache is hidden.
Please re-hide the cache so it is not visable.
Return to path, and continue on in the same direction you were going, this will lead you back to the car park.
Have Fun! If you are a tourist, and would like to do this cache but can't because you dont have a torch, please log a note saying so. If there is demand I may look at buying some torches and hiding them somewhere for people to use.
