The cache has been inspired by the Communications Tower. Parking is available at the top of One Tree Hill, near the rotunda, and the cache is a short walk, but watch out for traffic and other parking opportunities.
This is a nanno cache, byo pen.
Watch out for muggles, snakes, kangaroos and other wildlife. Ridge Track is poorly maintained, and I suggest 2wd vehicles don't use it, experience tells me, to use this route by foot, but there are other ways to the cache.
