I have not been there. As for trees it depends on time of year. certain times of the year trees drop sap. That can be a bear to clean up.

Google maps show what looks to be a a quarry on each side of them. If you are close enough yo may want to do a drive by. From a sat view some of the sites looks nice, but some may be hard to get in. Interesting their video almost show nothing about the park itself.
