Majorelle Gardens are stunning. The Menara gardens are more like an orchard and the Agdal gardens were closed as the King was in residence. However, the carriage ride is a good way to spend an hour or so and the tour was still good value for money.
A good opportunity to get out of the main city of Marrakech and see some of the dessert and the Atlas mountains. Sadly the tour seemed to focus more on getting you to spend money with the local artisans than seeing the sites of the Ourika Valley, however seeing how Argan oil is made was interesting.
