Palmyra (the roman name) is known as Tadmor to the Syrians. Both mean the same thing - date palm. The name comes from the lush oasis adjacent to the city which is home to some million date palms. It is the only oasis in Syria.
The major tourist attraction of the area is the stunning ruins - the most famous and well-preserved of which are the Temple of Bel, the colonnade, the funerary towers, the hypogeum of 3 brothers, and the Arab castle. All are within a few kilometers of each other.
Easily accessible from Damascus by bus. Fare is a few hundred pounds (several $US). The tour takes about 3 1/2 hours.
Tour buses abound, or locals will offer rides if you are willing to haggle.

There are no ATMs in Palmyra, and the local exchange office will not change traveller's cheques. Make sure you have sufficient cash for your time in Palmyra.
The New Palmyra Restaurant / Pancake House is a real treat, located on the main street in the tourist part of town. The extensive menu of local foods are very flavourful, and the pancakes would be desireable anywhere, let alone after eating nothing but Arab breakfasts for a few days.
