The price of a ticket only for the garden is 7 Euro and 3 more for the Berber Museum and 18 Euro for everything.
But if you fo not want to stand in a queue, you can buy them on line, but that is quite expensive. But it saves you a lot of time.
The gardens are beautiful and absolutely worthwhile to visit. The Berber museum is interesting too.
And don't forget to see the house and gardens of Yves St Laurent which you only can reach through the second exit!!

This is well worth a visit so much to see and the little cafe is lovely hot chocolate to die for!!!!

Don’t miss the Jardin Majorelle. It’s well worth the 180 MDH (combined ticket cost inclusive of the Berber Museum and the YSL Museum). Tip, if the line outside of the gardens is too long and you also wish to see the Museum, do the YSL Museum first (buy a combined ticket there) as the lines are usually much shorter, and that combined ticket allows you to skip the long lines at the Jardin. Go!

Very crowded but worth the wait. Beautifully laid out gardens with fascinating range of plants. Good restaurant and Berber Museum is worth spending time over. .....also Yves Saint Laurent collection museum.
