How much walking is involved in Petra?
On our day tours there are about 4 hours of walking on relatively leveled terrain.
Upon entry to the site, your Petra tour guide will stop every now & then and offer his explanations on sites seen & visited along the dry river bed. Upon exiting the archaeological park, it is a free, non-guided walk out back to the gate where the group will meet at a set time & proceed to lunch in one the Petra hotels.
For those who feel tired horse carriages are available on site. Horse carriage is not included in tour fee & you will need to lead a bargain with the Bedouins. (Ask your Jordanian guide to help you with the bargain)
