That was the plan or at least an attempt to show how it was like.
There is a nearer desert 2 hours away from Marrakech but it doesn't have tall sand dunes, that's what I was told from a local in Marrakech. There are 2 routes to Merzouga, but you have to join a tour group or have your own car. Either way, there are interesting stuff along the way.
One day!
