The Southern Desert is a region of Jordan, and the site of Jordan's biggest attraction: Petra. Petra is the fabled "rose red city, half as old as time." It's a well known ancient Nabataean city in the south of Jordan, and due to its breathtaking grandeur and fabulously preserved ruins, Petra was recognized as a World Heritage Site by UNESCO in 1985. The only modes of transport allowed within Petra are on two feet or on four feet (camel, donkey, or horse). When entering Petra, there is a brief hike down towards the Siq. Horses will be available for travel to the entrance of the Siq, or you can choose to take a horse-drawn buggy through the Siq (a distance of about .9 kilometers) and down to the Treasury. The prices for such rides are not set and are extremely negotiable, depending on one's bargaining abilities. Once you arrive at the Treasury, there will be many camel and donkey owners jockeying for your business. Be prepared to do some bargaining and don't pay more than 10 JD, a more reasonable price is around 3 JD a person. Often times the owner will drop his price in half simply by hearing a few phrases in Arabic. Camel or donkey transport should be seriously considered. Riding a camel is a unique experience on more level ground, but a donkey is recommended for more ambitious climbs, such as the ones to the High Place or the Monastery. However if you are reasonably fit and the weather is good, the walk is quite nice.
