Amtoudi
This oasis is about 105 miles from Fort Bou-Jerif, approximately 2.5 hours by car, located at the very end of a track, back to a cliff. You have tp see the source of the oued, at the end of a path in the shade, you'll be able to swim in the numerous natural pools there…
You have to go up and visit the agadir (an attic/safe built on top of a peak), either by foot, or on a donkey, but either way the spectacle is guaranteed.
Not too far away, in Foum El Hasn, you'll be able to admire some of the oldest rupestrian art of the region. You can see more recent work to the East, where numerous sites are visible.
