The design of this passage way was to protect the city. Our tour guide took his time explaining some of its details, including the water system. It was an great experience seeing the different colour and shape of rock formation along the path. The most vivid experience was definitely, hearing the sound of horse carriage coming, waiting, waiting, then, one or two of them coming toward you at full speed. It was like back in time.

Before entering the Siq you will need to travel on a wide valley known as the Bab as-Sīq. You can either walk or ride a horse. The local horsemen will ask for a 7USD tip for the short ride. The Siq is the main entrance to the ancient Nabatean city of Petra. It is a dim, narrow gorge (in some points no more than 3 meters (10 ft) wide) and winds its way approximately 1.2 kilometers and ends at Petra's most elaborate ruin, Al Khazneh (the Treasury). Most tourist would walk directly and swiftly to get to the treasury probably because of time constraints. We were fortunate to have had a guide who narrated the historical details as we walked along the Siq. You will find ancient carvings along the way. It was an amazing magical walk before entering the main city. Walk slowly and enjoy the spectacular views of the Siq if you have the time. This is the path that the advance Nabateans and Romans used in the old times to get to the main city. It is a mystery why the great city of Petra suddenly ended.

The Siq is the entryway that leads from the ancient "main road" into the city itself. Coming through here, it's hard to believe something more amazing awaits you at the end of this walk, but it's true. I recommended walking rather than riding through here, so you can take your time admiring the aqueducts, rock formations, and other formations. However, don't meander too slowly; this is just the beginning of a very amazing day, and I can guarantee you'll want enough time to properly explore as much of the city as you can.
