Post 23 is an orienteering post. I Made the marker to allow a competition on the course in the park. In total 12 of the 24 posts had disappeared but not all the new markers have a cache.
Cranford Countryside Park is a 144-acre public park in Cranford. Situated in close proximity to Heathrow Airport it is bordered by the M4 to the north, and by the town of and Cranford to the and South East respectively. Although its namesake Cranford is within the London Borough of Hounslow the park itself is geographically in fact part of the London Borough of Hillingdon, as it straddles the southernmost point of this borough. Despite this. Although the park is in an urban location, it is vehicle-accessible only by a small road before the motorway entrance slip junction 3.
