This was the absolute trip of a life time and definitely falls in my top three destinations! Starting in Marrakech and then doing a 3 day Sahara desert tour with RAK adventures, I have so much to recommend:

1. When visiting Marrakech, make sure you stay in a riad, a traditional Moroccan house or palace with an interior garden or courtyard. I stayed at Riad Alwachma where they welcomed me with Moroccan mint tea and I even had a traditional hammam spa for the first time there too.
   

   
2. See the Kotoubia mosque and medina both in the day and at night because of the different atmosphere you can experience. Don’t get ripped off by the people trying to get you to tour around on horse carriages like I did because you can easily walk around yourself and make sure you bargain at the Medina. At the Medina you’ll be able to have the cheapest and freshest orange juice in your life! Other things to do but not a must in my opinion: Bahia Palace (had no signs to indicate what I was looking at) and Majorelle garden (completely man made).
   

   
   

   
3. A restaurant I would recommend in the Medina is Le Marrakchi. It’s a bit more fancy and pricy but a good start to getting a full sample of Moroccan food. They gave you so much to try for a set price and there was a little band playing which was a nice touch.
   

   

   

4. Learn how argan oil is produced, carpets are made and the use of fire to change the colour of natural plant dye to use in art. Consider buying these local products!
   

   

   
5. Join the 3 day sahara desert tour to
   • Explore the High Atlas mountains, seen as snowcaps in the background as well. 
   • Pass Berber villages
   • View the Tizi n Tichka pass
   • Visit Unesco kasbah of Ait Benhaddou
   • Visit Ouarzazate movie studios
   • Visit Dades and Todra Gorges
     

     
   • Camel ride in Merzouga desert
     

     

     

     
   • Sleep in a desert camp which included a bonfire, and traditional berber music playing under the stars. Try sandboarding too!
     

     

     

     

     
   • Wake up early to catch sun rise behind the dunes 

Others: Some people say it is worth visiting a tannery where they tan animal skin (leather) but I was too afraid of the smell!

Note: The only time I felt a bit uncomfortable was in Marrakesh where it was very crowded, dusty and people kept trying to convince you to buy stuff. But once I went out into the country side, my trip was just incredible.
