"What's most amazing about Petra is the colour of the rocks and how the light reflects upon them," says Cohen. "I definitely recommend a donkey ride to explore more - it's a wobbly journey, but memorable." Named one of the new seven wonders of the world, this beautiful and ancient city seems to be on everyone's bucket list - and for good reason. The Treasury and the Monastery are very well preserved, especially considering the fact that they were built in 312 BC Safety concerns and physical obstacles have left many travellers wondering if the Rose City, as it's called, is worth a visit. Despite the long trek - expect an approximately 1,000-foot vertical climb to see the monastery - the attraction comes highly recommended. Tip: Plan to spend at least a full day (if not two) here.
