The first is a week-long camel trek to near the Morocco-Algeria border. The second is a 12-day hike through several villages in the Western Atlas Mountains, including Mt. Toubkal.
Accomodations are fairly rugged, including tent camping and stays at riads/guesthouses in some villages. Food is mostly provided by the trip operators.
The hiking portion is supposedly fairly physically demanding, though I have not attempted it myself. Most days will include at least a couple hours of walking in the sun.
