Have you checked out Pinterest? I just did, after attending a Statewide conference of the California League of Park Associations. They're the folks currently providing interpretive services and docents in California's State Parks, and who are responding to the closure of these parks by stepping up to operating agreements with the State.
The good news is that we all came away from the San Diego conference re-charged, and despite even more bad news from the Governor, dedicated to fighting hard to keep the parks open and accessible.
Here's some great photos and contacts accessible on Pinterest through a search of "California coast".
