Solano Land Trust owns Rockville Trails, a lovely open space area that they saved from development. It is just to the north of Rockville Hills Regional Park. At this time, access is limited to docent-led hikes. You can check out what events Solano Land Trust has coming up on their website.
Understandably, there is often confusion between "Rockville Park" and "Rockville Trails." My understanding is that the Land Trust folks are considering a name change to help people out.

Inside Rockville Trails are many interesting geological features, including a view of the Cordelia Fault.
