I'd think you can spend only a couple hours there, at most. There are trails, but not well marked. There appeared to be trails across the road, but I did not see a map. People seem to explore the rocks following their own routes. There is a nice creek there and hemlock forest. Some hemlocks are old growth. The rocks are a local park, that is not to state park standards. The rocks themselves have been kept in a natural setting. Definitely worth seeing, but it won't be for a whole day.
