Traveler please note that the current guidebooks to the Middle East have many errors. Below is an email from Craig of Travelvice.com on how to travel from Damascus, Syria to Amman, Jordan. I followed this advice and it is right on.
The following is information on how to travel from Damascus to Amman from Craig of Travelvice.com
The new Al-Samariyeh terminal (Mezzeh West) has replaced the old Baramke terminal. It’s on the far western outskirts of the city. This is where you catch buses going to southern destinations such as Bosra, Der’a and Suweida, and buses and service taxis to Beirut and Amman, along with some international services to Jordan, Lebanon, Egypt and the Gulf. In addition, there are several other microbus and minibus stations serving regional destinations.
I departed Damascus at 14:30 and didn’t arrive until 22:30! Not a quick trip! Buses leave at 8:30, 14:30 & 16:30.
As usual, Syria charges the 500 syrian pound exit fee, and Jordan will charge 10 JD to enter (you will have to exchange to pay in local currency).
The ‘Challenge’ bus company that I used dumps you not a bus terminal, but in the middle of the street where their office is. It’s a fucking frenzy, and it’s highly suggested that you change extra cash at the border because finding that initial ATM in the city can be a bit hard. Arrive with cash so that you can take a metered taxi, unlike my hassle that I got sucked into!
