I definitely recommend you visit Madain Saleh if you are living in Saudi. A group of us booked two rooms at Al-Arac hotel. The accommodations were very nice, though they seemed to not have our booking on file, though we booked with an approved website. Pricing for the room was reasonable, but food was pricey. I highly recommend our tour guide, Saeed Al-Johani (email@example.com), who arranged our permits into the heritage site and gave us a great tour of the area, museum, and other nearby locations. There was no rush from him and he was extremely knowledgeable of the area. On top of all of that, he charged a good, reasonable price. Make sure to bring your camera, decent shoes for climbing, and a light jacket for brisk weather, Honestly, this place is gorgeous, the geology is amazing, and the history behind it all in very enlightening!
