The iconic walk into the ancient city of Petra primarily follows the Siq, a dramatic, narrow gorge that serves as the main entrance to the archaeological site. From the main Visitor Center to the Treasury (Al-Khazneh), the walk is approximately 2.2 kilometers (1.4 miles) in total. The Siq itself makes up about 1.2 kilometers of this journey. For an average walker, this takes roughly 30 to 45 minutes each way, depending on how often you stop to admire the towering sandstone cliffs that rise up to 80 meters high. The path is relatively flat and paved with smooth stones and gravel, but the desert heat can make it feel more taxing. If you continue beyond the Treasury to the Monastery (Ad Deir), be prepared for a much more strenuous hike involving over 800 hand-carved stone steps, which adds another hour or more to your journey. Most visitors spend a full day walking, covering 10–15 kilometers as they explore the vast "Rose City."
