A Habous tour usually means a guided walk through Casablanca's old medina quarter, the Habous, built by the French in the 1920s in a neat, tourist-friendly version of Moroccan architecture. Expect to spend 1.5–2 hours strolling arcades lined with shops selling spices, olives, traditional clothing, brassware, and sweets. A decent guide will explain the history, point out the royal palace entrance, and stop at a few artisan workshops or a small mosque exterior. It's low-key, fairly quiet compared with Marrakech, and feels more like a relaxed neighborhood stroll than a hard-sell bazaar experience. Groups are small; you'll probably share the guide with 4–8 other travelers.
Best time is spring (March–May) or autumn (October–November) when it's mild and pleasant for walking. Summers are hot and glare off the white walls is brutal; winters can be chilly and damp. Expect to pay around 250–450 MAD per person for a private or semi-private half-day tour including the Habous, maybe a quick stop at the Central Market or a viewpoint. Cheaper group tours exist but often feel rushed.
Tip: Choose a tour that starts in the morning when the light is good and shops are opening; skip any version that bundles in a long carpet-factory visit unless you actually enjoy haggling. Wear comfortable shoes—the pavement is uneven—and bring small change for spontaneous spice or date purchases. It's a solid half-day activity if you want a gentle introduction to Moroccan medina life without the intensity of Fez or Marrakech.
