This is a lovely walk through the woods and fields around Wretham. The whole walk is about 4 miles in distance. The walk follows part of the Wretham wildlife trail, it is mostly well sign posted but crossing the farmer's field between cache 5 and cache 6 can be a bit of a challenge if you don't know the route. After finding cache number 5, cross the first field, then turn right and cross the small footbridge over the ditch (you will see a footpath sign here). Then walk straight across the second field, and along the edge of the third field, heading towards the house.These caches are hidden with the permission of East of England forestry commission.
