The fourth cache in this series is situated on a public footpath near the tiny village of Burtons Green. You are looking for a small plastic click-lock container with room for small trades, coins and TBs.
Inside this cache you will find part of the information needed to find the 'Jewel' bonus cache.
If you are doing the whole series, I suggest you park in the village of Greenstead Green and join the footpath at: N 51 55.124; E 0 38.899
Update: 31 August 2011
I have completely replaced this series today. All new containers, freshly stocked and with new log books.
Update: 3 Sept 2012
Please be careful as some parts of this walk can get very overgrown with nettles and brambles in the summer.
