Azraq has an interesting geological history. It was once a vast oasis, its pools filled by a complex network of aquifers fed mainly from the Jebel Druze area of southern Syria – the waters taking up to 50 years en route. Surrounding the oasis is about 60 sq.m. of silt, beneath which is a vast concentration of salt
Azraq is a unique wetland oasis located in the heart of the semi-arid Jordanian eastern desert, one of several beautiful nature reserves managed by the RSCN. Its attractions include several natural and ancient-built pools, a seasonally flooded marshland, and a large mudflat known as Qa'a Al-Azraq. A wide variety of birds stop at the reserve each year to rest during their arduous migration routes between Asia and Africa. Some stay for the winter or breed within the protected areas of the wetland.
The best time to visit Al-Azraq is in late autumn, winter or spring. Winter rains often create pools and marshes over the reserve, which continue to attract many seasonal species of birds. The success of bird-watching visits depends largely on the amount of water that has accumulated in the reserve.
