Hi! I will be spending a week in Redlands, CA for a workshop and plan on spending 7-9 days driving north to hit up these parks afterward. I've never been in that area before... the only thing I know I want to do is an overnight backpack Hetch Hetchy and i'll probably want to see the tourist stuff. I'm looking for a good itinerary or must-do's for me to build an itinerary and good camp spots in or out of parks. Should I bring a bike? Would like to make reservations before the end of March. Any input is greatly appreciated.
