also Zekreet area is nice to camp out,
if you drive from sealine resort to inland sea by the coastline (thru the dunes and not the dessert highway) there are a few nice camp spots as well witch are clean and not crowded later on the day.

we tent to leave at midday from sealine resort do a bit offroading / dune bashing and then camp out with and have a dive in sea, some stay overnight as well (me included)

you do need a real 4x4 tough to do so, for zekreet area a crossover will work fine
