Open Question: wild camping scotland?

Me and a few friends are wild camping in Western Scotland soon and we have no idea where to start. Can anyone recommend any beautiful and secluded spots to pitch our tents?
Would quite like to stay near a loch or possibly a remote beach.

We are driving so we need a spot to park the car which isnt too far from the spot if possible.

Thanks!!
