Zenaga is the oldest of Figuig's seven ksour and the best place to begin exploring the town. Its high earthen walls and watchtowers are in good condition, and a platform above the main gate gives a commanding view over the whole oasis — the sea of date palms below, the surrounding mountains, and (on clear days) the Algerian desert beyond.
The interior is a labyrinth of narrow alleys, arched passageways and earthen houses built close together to provide shade. Some are inhabited; others are gradually falling back into the earth. Walking through without a guide is easy enough — get lost, then find your way back by heading toward the sound of water in the irrigation channels.
