How difficult is this trip? I will be traveling with my 80 year old parents.
There is horse drawn cart from entrance of Petra to the treasury. You can bargain for the right fare. Great place to visit for sure.
There is quite a bit of walking in Petra to get from the bus to the actual "Treasury." It is relatively smooth and level, but long and somewhat gradually uphill on the return, so it depends on the condition of the person on the tour.
