Camden Park is a 12 acre open space in Fearrington Village that features walking paths, a pollinator garden, park benches, and two ponds connected by a waterfall. A detailed description of the flora in the park can be found on the Fearrington Homeowner's Association web site. As for fauna, you are likely to meet a few dogs being walked by their owners; if you are lucky you may catch a glimpse of the resident heron fishing in one of the ponds; and in any case, you will definitely meet one other species of fauna not mentioned in the first Fearrington Fauna cache.
Bring your own writing implement. Please be discreet while you search, as there may be several muggles walking by.
From the recommended parking location it's only a short walk to the cache, but it's worth taking time to explore the whole park.
