While you can physically wear sandals in Petra, it is highly discouraged for a high-fidelity exploration of the archaeological site. Petra is a massive, rugged desert terrain consisting of deep sand, uneven cobblestones, and steep, slippery rock stairs. A standard day of sightseeing often involves walking over 10 to 15 miles. Sandals offer very little arch support and leave your feet exposed to the scorching sun, abrasive sand, and potential "donkey droppings" found along the main trails. If you are planning to hike to the "Monastery" or the "High Place of Sacrifice," you will be navigating over 800 hand-cut stone steps where traction is essential. If you absolutely must wear sandals, they should be high-quality "adventure sandals" with thick soles and secure ankle straps (like Tevas or Chacos). Flip-flops are a recipe for blisters and twisted ankles. In 2026, most experienced travelers recommend a breathable pair of light hiking boots or sturdy trail running shoes to protect your feet from the heat of the Jordanian desert and the sharp edges of the Nabataean sandstone.
