The Nitzanim Sand Dune Nature Reserve is a 21,600 dunam area within the Nitzanim Sands [he] area between Ashdod and Ashkelon on the Southern Coastal Plain of the Israeli Mediterranean Sea coast.

[1] The Reserve includes a small settlement of Nitzan located in place of the Nitzanim kibbutz, which was resettled some 3-4 km to the south.

The reserve is split in two parts by the Nahal Evtah (Evtach, Avtah) (Hebrew: נחל אבטח) wadi (Wadi el Ibtah) which leads to the Nitzanim Beach by the sea.

The area south of the stream is designated for the IDF recruit training base Batar Nitzanim [he] (Camp Yehoshua)[5] and is closed to public.

The northern part is open to public all year round free of charge.
