We have done both the drive yourself cave tour and the eye-opening guided trip up the switchbacks to the heights of the quarries -- we have a niece coming to visit who wants no part of heights and switchbacks, so the winner is the drive yourself. We did by just driving up to the ticket office and waiting for a tour to begin. Would like to do a little more planning this time, but can not find anything on line for information. Anyone who can point me to a site that would help the planning??
