Please note that the first 5 caches in the series are placed within the park, and the gates are locked between 6pm and 6am daily.
The total distance is approximately 3 miles. There is a final mystery cache (GC40JJN) which requires the collection of letters and numbers as you progress. I recommend parking along Cedar Way and doing the circuit in number order (details are on the first cache page).
Ditton Park was part of the Manor of Ditton and once belonged to the crown in the reign of Queen Elizabeth I. It then belonged to Sir Ralph Winwood who in turn passed it to Ralph Montagu, 1st Duke of Montagu, through marriage.
The present Ditton Park House (known locally as Ditton Castle) was built around 1500, but was badly damaged by fire in 1812. In 1917 the property was taken over for the Admiralty Compass Observatory, which used the house and its immediate grounds until it was sold to a software company in the 1990s.
In 1920 the park started to be used for radio research and these activities eventually lead to the formation of the Radio Research Station. It was here in 1935 that the idea for the development of British Radar defense system was conceived.
