Amzi, like Ait Irghite, is a small mountain village in the Atlas foothills north of Amizmiz. Amzi, though, is much smaller (only 60 or so inhabitants) and much closer to Amizmiz than Ait Irghite, making it perfect for a daytrip. The walk up is pretty spectacular, with the fields of barely and wheat swaying in the wind and the clouds descending down among the mountain peaks.
You have to go with a guide who knows the locals, and I'd recommend Berber Travel Adventures ('http://berberadventures.com/'). They arranged a visit to a local family who cooked some absolutely delicious traditional clay-oven bread and fixed us a "Berber Omelet," a clay pot filled with spices, tomatoes, onions, and, of course, eggs from their own chickens. It was one of the best things I tried in all of Morocco! The guides that take you there are very friendly, funny, and speak great English. They also show you a side of Morocco you normally wouldn't see, and make sure that the small Berber mountain families receive their fair share of the money for the trip.
