The valleys of Asni, Imlil (along the Mizane Valley), Tacheddirt (Imenane Valley) and Tizi Oussem/Ouirgane (Azzadene Valley) offer fine walks, which you might consider doing to acclimatize yourself before tackling Toubkal or other high peaks. They are all much easier if you walk them downhill.
From late spring to late autumn (see Atlas trekking practicalities), the region’s trails are accessible for any reasonably fit walker. Mule tracks that allow one to navigate around the mountain valleys are well contoured and are usually in excellent condition. Additionally, there’s a network of village gîtes, houses and CAF refuges (small huts) for accommodation, which generally makes camping unnecessary unless you’re traipsing far away from the villages.
