Yes, you can absolutely visit Petra without a tour in 2026. The site is well-marked, safe, and easily navigable for independent travelers. You can purchase your tickets at the Visitor Center (free with a Jordan Pass if staying 2+ nights) and explore the main trail from the Siq to the Treasury and up to the Monastery at your own pace. While a guide can provide deep historical context and show you hidden viewpoints, the main paths are clearly defined. For 2026 visitors, the "independent" approach is often preferred as it allows you to arrive at "rope drop" (6:00 AM) to beat the tour buses. If you decide you want a guide once inside, licensed guides are available for hire at the entrance for fixed rates. Solo travelers and families alike find the site very accessible, though you should carry a digital or paper map to ensure you don't miss the smaller royal tombs tucked into the cliffsides.
