Four days in Ojai - girl's trip help needed

My adult daughter and I are planning on driving down from SF to spend four days in Ojai, late March. I know nothing about the area, other than what I've read on TA, and would love some planning help. We'd love to go horseback riding, take a good long hike, perhaps do some biking, and eat wonderful wonderful food (we're big foodies). Thinking of staying at the Ojai Valley Inn (they have a third night three promotion going, plus we need a room with two beds). Any suggestions, help, ideas would be most welcome.

Thanks
