None of the caches contain pens, please bring your own writing implement.
There is also a bonus cache whose location is contained in clues on logbooks around the circuit. Be sure to note the clues as you find them.
Beyond this cache there is a steep climb up to bug hill.
To avoid this and shorten the circuit to just over 4 miles, continue down the main path and past the golf club headquarters until you reach the bridleway on the far side of the golf course. Turn right onto this and make your way along to cache #17.
Otherwise turn right approximately 100m beyond this cache (At point R1 - it's easy to miss!) and climb the hill all the way to the road then turn left towards cache #14.
Once on the road, you can also collect "Coal Post #175 (GC1Q7NW)".
