If you forget it, don't worry - just reuse a plastic bottle you've purchased on arrival. The other good thing is that many of the hotels in Petra and Wadi Rum have installed water purification systems for their guests, which means you can drink water from the tap that isn't just safe but tastes pleasant.

You should not drink tap water in Petra or anywhere else in Jordan. While the water in major Jordanian cities is often treated and technically safe at the source, the distribution systems and aging pipes can introduce contaminants, and the mineral content is significantly different from what most Western travelers are accustomed to. Drinking tap water often leads to "Traveler's Tummy" or more severe gastrointestinal issues. It is strongly recommended to use bottled water for drinking and even for brushing your teeth if you have a sensitive stomach. In 2026, many eco-conscious hotels in the Petra/Wadi Musa area have installed high-quality filtration systems or provide large water carboys to reduce plastic waste; always ask your hotel staff if the filtered water provided is safe for consumption. When exploring the ancient city of Petra itself, be sure to carry a significant supply of bottled water, as the dry desert heat can lead to rapid dehydration during the long hikes to the Monastery or the High Place of Sacrifice.
