Dirat al-Tulul (), and called locally in Levantine Arabic Diret el Tlà «l, is a lava region in southern Syria. It lies about 65 kilometers east of Damascus, located in the central part of the Rif Dimashq administrative district (governorate or muhafazat).
Dirat al-Tulul forms the northernmost extension of the massive alkaline lava field of Harrat al-Shamah. To the south it is bordered by the al-Safa lava field, another part of the massive Harrat al-Shamah lava region. Dirat al-Tulul also forms the western part of the Syrian steppe known as Badiyat al-Sham.
Dirat al-Tulul contains more than 32 cinder cones, known as Tell (Arabic for hill).
This region receives between 100 and 200 mm. of precipitation per year and it is sparsely populated, due to its aridity and rocky terrain. It is used for pasture by nomadic and seminomadic Bedouin.
