A camera is a must! In addition to all mentioned above....Duct tape can come in handy (I make a small 'roll' of my own of about 20 ft.), Benadryl for those nights when strange sounds/enviroment keep you from sleeping well (just don't take after midnight or you'll risk being tired in the morning), Small first aid kit with bandaids/ointment/large pad/ace wrap/advil etc, a bandana (has multiple uses), small notepad and pen, hat for off bike wear if you're camping.
Have fun!
