There is one high alpine cabin in the Atlas mountains called the Neltner Refuge.  It is located at 3207m on the flank of Mt Toubkal and is a great jumping off point for climbing the highest peak in the Atlas. Other peaks can be reached within a day from the cabin also, and the approach from Imlil can be done in a day with the help of mules. The cabin has no heating or electricity but you may be able to get meals. Check in Imlil.
