Read what other Viator.com travelers think about the Private Tour: Desert Castle Tour of Eastern Jordan from Amman. What they loved, what they liked and what they think could be improved, it's all here to help you make the most of your next trip.
For this tour, a driver takes you from your hotel out to the three sites and pays admission. You're generally on your own to tour the actual sites (guides can be hired, but you really don't need them).
My driver was prompt, spoke English well, and I enjoyed the conversation with him along the way. He did tour the sites with me, though technically he wasn't a guide. I had plenty of time at each site - I actually got 5 hours for the price of 4.
I suspect that the differing reviews depend on the luck of the draw with the driver. In any event, the sites themselves are worth spending the morning visiting, and it's a chance to see a different side of Jordan.
And where else are you going to get a picture showing the distances to the Saudi Arabia and Iraq borders?
Very interesting. The castles, completely different from one another, are outside the normal tourists' routes. Even our kind driver did not know them! We got to see the beautiful panorama of Jordan.
