If you are seeking this at night, be aware there is a steep drop to the road below several steps off the path, you need not go that far from the path.
There are a few of these linear parks around, but they aren't well publicized. I've walked this one before and always thought this was well suited to a cache. The better end is too close to an existing cache, but this end is just about as good, if a bit narrower.
Cache does not require anything perilous, such as tree climbing or trying to scale or descend the slope to the road. It's a couple steps off the paved path and should be easy reach for all but the shortest.
There is parking at either end of the path, if you can get it before the park-fee dodgers grab it all. There is a house nearby, so if you seek at night please be quiet and use a minimum of flashlights. Cache should be a quick find.
