Yes, Little Petra (Siq al-Barid) is absolutely worth visiting in 2026, especially as a "quiet" alternative or a historical prelude to the main Petra site. Located just 15 minutes north of Wadi Musa, it served as a "suburb" and trading post where ancient caravans would rest before entering the main city. While much smaller than its famous neighbor, Little Petra features stunning Nabatean carvings, including the rare and beautifully preserved "Painted House" frescos, which depict intricate vines and birds. In 2026, many savvy travelers use Little Petra as the starting point for the "Back Door" hike to the Monastery; this route allows you to enter the main Petra site from the opposite direction, avoiding the crowds in the Siq and offering a spectacular, high-altitude approach to the monuments. Since it is free to enter with a Jordan Pass and takes only about an hour to explore, it provides an "authentic" and relaxed perspective of Nabatean life that the busier main site often lacks.
