yeah the three day limit would cramp it up way too much...but there are plenty of awesome places to visit and experience the richness of Moroccan culture. The only tough part is that I was quite south of Casablanca most of the time and only stopped there on the day that I flew out. If you dont mind taking a bit of a bus ride (a cultural experince in itself) then there are all sort of great places on the coast if you head south. I would personally suggest Agadir and Taghazout as I spent a week between the two and they blew me away (Taghazout more so as it was without ANY tourists). But i also enjoyed Essaouira as it had a cool and laid back atomosphere. This would be a little bit closer to Casablanca but also more touristy. There were several towns that I dont even remember the name of but would get off the bus and ask if anyone knew someone that would rent a room. I almost stayed in a beach city called Safi as it is supposed to have some decent surf but had locals recommend against it because of its rougher scene. Casablanca isnt too far off from the city of Fez and the little town of Chefcouan (spelling??) where you wont run out of cultural excitement. If you stay inside the Old Medina (important to be inside the oldcity walls) I promise you wont be disappointed by the maze of narrow streets and colorful tanneries (there are some pictures on my profile). I wish i knew more about the hiking scene up north to help you out. Im into both hiking and rock climbing and there is enough of both in Morocco. I hope you enjoy yourself!! Let me know if there is anything else I can help you with!! But your best option might be to show up with no plans, ask some locals, and run with suggestions! Either way, busses are cheap, people are friendly, and there's a big country to explore!!

Great to hear that you are interested in doing some Moroccan hiking. The only areas that I was able to hike were in the High Atlas Range which is south of Marrakesh and stretches all the way to Algeria. If you have the time, there is a gorgeous peak, Jbel Toubkal, that also happens to be the tallest peak in Northern Africa. Its a little tough on the lungs with the altitude and all but its not technical at all. In order to get there, you would take a local bus from Bab er-Rob in outer Marrakesh to Asni and then a taxi from Asni to Imlil (the base of the mountain). Thats the cheapest way to do it but it would be super easy to just grab a grand taxi from Marakesh to Imlil--make sure to set the price before you leave!!! I used to have a Lonely Planet book that gave a better description of it all and the hike itself. But its a 3-day hike with the travelling and you said that you were crunched for time so i dont know if this is the best fit. As far as the rest of Morocco's hiking, Im pretty uninformed. I know that there are some cool places to hike around Chefchaouen (a cool all blue town a little closer to Casablanca) and the town itself is a neat experience. Up in that area, there is also the Rif mountain range that should have some nice areas. Good luck with your travels and let me know if you have any more questions! I'd love to help you out!

Your scuba photos are really lovely! That looks like so much fun. :)
