The Monastery Route in Petra is a challenging but rewarding trek to reach the awe-inspiring Monastery monument. The route involves a steep climb with 800 steps, passing by a holy spring and offering stunning views of the Petra basin and Wadi Araba. Despite the temptation of donkey rides, it's best to walk to preserve the ancient sandstone steps. Once at the Monastery, visitors can marvel at the massive facade and explore nearby caves, tombs, and cisterns. The descent back to Petra should be done before sunset, as the rocky terrain can be treacherous in the dark.
