Where do you suggest to go for gorgeous natural views in the bay area?

In particular, I visited this one place along Skyline Boulevard and it was a huge rock cliff and it overlooked a (redwood?) forest...it took about 1-20 minutes to walk to the cliff from where we parked. I haven't been there in years and don't remember where it is...oh I also remember that the cliff wasn't dirt but a blackish type of rock. PLEASE HELP!!! I want to find this place for a photography ignment. THANKS!!!
