The posted coordinates are for the entrance to a picturesque churchyard in Henley. There is limited free parking but it can get very busy so we suggest parking on the Prince Harry Road Car Park a short walk away. To get the coordinates for the cache, you need to find a couple of gravestones and gather some information. Both are visible from the path so won't require you to stray too close to the graves. The information you require is on the gaves of John Aubrey Hawkes (JAH) and Thomas Rainbow (TR) and is as follows:
N 52 17.ABC W001 46.DEF
A= Month TR died
B3= Date TR died
CC= Day JAH died
188D= Year TR died
E= Number of letters in country where JAH died
191F= Year JAH died
