Only spots I've been have had toilets..
Sometimes a bit of a challenge, but a bit of roaming has found a soft spot....diggable anyway !!
Last trip we were on encountered a couple of camp sites with rock about 3 inches of sand covering,
couldn't even drive tent pegs in.
Searched everywhere and I mean everywhere and it was all the same just rock covered
by a thin layer of sand, a ramset would have been good to drive in some nails to
tie the tent guys to for the ones tenting. The tent occupants had to lay on the wind side
of the touring tents all night to side to stop them blowing over:)
