You a looking for a small cache with room for log book only. I frequently drive past this location and had seen the small car park and wondered what it was for. On a recent walk I discovered a hidden toilet block by the pond amongst the trees. In the current climate these are fast disappearing so may soon become a rarity. Enjoy finding the cache, taking a comfort break and then thoroughly wash your hands! Perhaps this can be the start of a new geocaching series 🤣
