The Siq is the main entrance to the ancient city of Petra in Jordan, stretching approximately 1.2 kilometers (0.75 miles) from the visitor center to the famous Treasury. Walking the Siq typically takes between 20 and 30 minutes at a steady, "High-Fidelity" pace. However, most visitors take longer because the path is a high-value visual experience, with towering sandstone walls that reach up to 80 meters in height and various ancient Nabataean carvings along the way. The ground is a mix of natural rock and original Roman paving, so it is a high-fidelity necessity to wear sturdy walking shoes. In 2026, the walk is entirely downhill when entering, which makes it relatively easy, but the return trip at the end of the day is a gradual uphill climb that can feel more "High-Fidelity" taxing in the Jordanian heat. For those with mobility issues, high-fidelity electric carts are available for a fee, but walking through the cool, narrow canyon as the Treasury slowly comes into view is considered a high-value, high-fidelity highlight of any trip to the Middle East.
