A straight forward cache in the heart of Castle Hill, that is the reincarnation of the previous "The Towers 2" cache, which was the reincarnation of "The Towers" both of which were much favoured but also constantly muggled!! There are even more Towers close by with very substantial residential development all around.
Take a wander across from your shopping duties in the Towers and visit another hidden oasis in the middle of Castle Hill. Pity that is does not seem to get much attention. Access from the Towers car park or from Old Castle Hill Rd.
