Jalo Oasis (or Jalu, or Gialo) is an oasis in Cyrenaica, Libya, located west of the Great Sand Sea and about 250 km south-east of the Gulf of Sidra. Quite large, 19 kilometres (12 mi) long and up to 11 kilometres (7 mi) wide,[1] it supports a number of settlements, the largest of which is the town of Jalu. Jalu was the administrative capital of the Jalu District from 1983 to 1988, at which time the area became part of the Ajdabiya District and as of 2007 is now part of the Al Wahat District.
