Hi,
I went to Essaouira in Morocco recently and I spent a week to discover the country during a horse trek. I would like to recommand the team who organised this trip, Sophie and Najib from Zouina-cheval. They are pretty good and my trip was as great as expected! So if you want to try yourself, i give you their link http://www.zouina-cheval.com/en/index_uk.html. I hope you will enjoy as much as i did!!!!
