Nearly everyone who goes to Amizmiz gets there via Marrakech. Within Marrakech, you'll need to take a "petit taxi" to the "Bab Er-Rob" taxi station that is just outside of town. Once you arrive at the taxi station, start asking for "Amizmiz" (which is pronounced AMZ-meez), and someone will eventually direct you to a "grand taxi" (an old Mercedes Benz) that is waiting to get filled up, at which point you'll depart. The normal fare is 12.5 Dirham. You can also find a "mini-bus" that takes a lot longer (because of more frequent stops) which costs only 10 Dirham. For those who are not as eager to sit squished for an hour's ride in the heat, feel free to pay for two places (hence 25 Dirham) and ask for the front passenger area to yourself (normally two people sit in the front passenger seat!).
Once you arrive at Amizmiz, you'll be able to get everywhere by foot.
Without doubt, if you can manage to get to Amizmiz on a Tuesday, you'll have the chance to see the weekly market ("souk" in Arabic). Here you'll a wide variety of people selling their goods: Berbers from the mountain villages and also local vendors as well. Nothing has a set price (except fresh food and produce), so be prepared to argue over prices.
Up into the hills, there are numerous small Berber villages that are worth visiting if you have the chance. Many of these still do not have running water or electricity, and you make see small children hauling huge plastic containers of water to their homes on donkeys. The people are incredibly hospital and generous.
There are different outfits that will help you get to some of these villages. The best by far is Berber Adventures, . You'll be able to schedule a day trip or more extended hike into the mountains. The prices are reasonable and the guide is extremely kind and used to working with westerners. He's not out to rip you off.
