The Treasury, or Al-Khazneh, in Petra, Jordan, is an iconic ancient Nabataean rock-cut monument. Reaching the Treasury involves navigating the Siq, a narrow gorge, which can be challenging for those with mobility issues; consider renting a horse or carriage for partial access. While exploring Petra independently is possible, a guided tour enriches the experience with historical context. Be aware that summer months can be intensely hot, making spring or fall ideal for visits. Entry to Petra, which includes the Treasury, requires purchasing a ticket, typically costing around 50-70 JOD (70-100 USD) for a day pass. Plan to spend at least 3-4 hours to appreciate the Treasury and surrounding areas, though a full day or more is recommended for exploring all of Petra.
