The Magna Carta Geocache is hidden within easy walking distance of the monument by the same name. Your clue is "dry but under water".
The Magna Carta Monument is just a few minutes walk from the John F Kennedy Memorial. Both lay on the slopes of the hill overlooking the River Thames at Runnymede - where Magna Carta was signed by King John in 1215. Both have an American connection, since the Magna Carta Monument was erected by the American Bar Association, "to commemorate Magna Carter symbol of freedom under law".
The nearest parking is near the river, but there is a free car park near the Air Force Memorial at the very top of the wooded ridge - which is well worth a quiet and thoughtful visit. The car park is at N 51° 26.216' W 000° 34.120' and access is from the village of Englefield Green - follow the brown signs to "Air Force Memorial". Turn right out of the car park, past the public toilets, to the Air Force Memorial on the left. Continue past it and bear left, for the public footpath into the National Trust woodland called Coopers Hill.
