Coordinates could be off due to tree cover, but there's an obvious climbing tree at the side of a trail. Cache is more than 6m up the tree.
You should only attempt this cache if you are a confident climber of trees. I placed it without any special gear, but many cachers will take one look at this one and say "No thanks".
There are a good number of branches near the cache, which should give you ample things to hang on to. I found it helpful to straddle a branch with both feet on a branch below it.
The Ridge Stile Park has a short trail system. This cache is on a loop. If you start at the signpost near the trailhead coordinates, you will travel a bit further eastwards beyond the cache, but keep following the trail. It will head south and when you get to a "T" junction you can follow the trail right to Ground Zero. The "lower" trail continues in a loop back to the Ridge Stile Park, and if you keep going west another 50m it will loop back to the starting point.
Congratulations to B2BRO on FTF!
