Geographically, the over 13,000km² Negev forms an inverted triangle whose western side is continuous with the desert of the Sinai peninsula, and whose eastern border is the WadiArabah.
Its central city is Beersheba (pop. around 200,000), in the north. The southern end is at the Gulf of Eilat and the resort town of Eilat. Other towns include Dimona and Mitzpe Ramon, and a number of Bedouin towns, including Rahat and Tel Sheva.
The Negev has a number of interesting cultural and geological features. Among these are three enormous, craterlike erosion cirques or machteshim, which are unique to the region: ha-Machtesh ha-Gadol ("The Big Crater"), ha-Machtesh ha-Katan ("The Small Crater") and Machtesh Ramon ("Ramon Crater"). The last is the biggest of all, in fact - it is probably the largest natural crater on Earth (it was not formed by asteroid impact).
The Negev covers the greater amount of Israel's official Southern District.
