Morocco is a really nice trip to do. I have done it a few times now in the 172. The first time I went I went down through France to Perpignan and then along the spanish coast to cross over at Gibralter. Route was Leicester-Cherbourg-Biarittz-Perpignan. Then into Spain to Le Juliana near Seville then Seville to Morocco.
Second time I went through Spain. Cherbourg-Biaritz-San Santander-Le Juliana and then across.
You do need an aircraft with good legs especially if routing through Spain as there are fewer options for refuel stops.
Morocco is really pretty and the Atlas mountains are worth a look. It is a very typical north african country and as much as I hate to agree with IO540 the quality of the food is a little shall we say 'debatable'! But it is just about edible!
It is a great trip to do.
