When we walked up this hill we had no intention of leaving a Cache but we thought it was amazing so decided to do so. We always carry spare chaching equipment in case we need to add a log or replace a damaged container.
To get the best out of this walk I would recomend you approuch it from the footpath from the west off the A40. We parked at May Hill Village Hall Car Park, which is free. The waypoint for the Car Park given will take you to a footpath to the East. If you take this route be sure to walk 500 meters after finding the cache to experience all the 'surprises'!
