A large car park by the edge of the ‘Sea’ with access to toilets and showers. It’s actually quite picturesque and others camp there too. If you have a hiking tent you can camp amongst the trees. Only 20NIS p/night
The only camping were knew of was 15km south, in Banana Beach, Nitzanem. We drove to the end of the sand carpark area and hid behind a dune for free – i think in summer you have to pay. The facilities weren’t open when we were there, but it’s pretty run down and dirty.
