Visited on holiday on October 2013. The location of the tomb is not marked or signposted anywhere in the park, but it is in the trees near the car park. Clearly some work was still going on then, or recently, as it was fenced off by some rather unattractive orange plastic. Medium sized stones of up to 5 feet length, arranged now in two elongated rows. The whole is in a hollow where it was (I presume) excavated and has a retaining wall on the higher side.
