Peats Ridge is an undulating north-south spur separating the Mooney Mooney Creek valley to the east from Mangrove Creek and its tributaries to the west. From the 1960s to the mid 80s, Peats Ridge Road formed part of Highway 1, following a circuitous route from Calga to Ourimbah until the opening of the more direct M1 link to Somersby. Since then, the ridge has reverted to a quiet rural setting dominated by market gardens, orchards and horse studs.
In a reserve at the corner of Peats Ridge Road and Ross Road is a rocky peak rising thirty metres above the surrounding plateau. At its summit is the "Moat" trig marker and this cache sits close by at a spot offering nice views across the fields and forest to the west. The trailhead waypoint provides relatively easy access into the reserve but there isn't much of a trail, more animal tracks I suppose, and once onto the incline it's up to you to find the best way to the top.
The cache, a plastic ammo can, is in a small cave just below the top, accessed down a sloping gap between the rocks. A pencil and sharpener are included. I used some rope as an extra hand-hold for getting to and from the cave but that was more as a precaution than a necessity. Take care, though, as the ledge is narrow and it's a long way down to the rocks below.
