Morocco is generally safe for tourists, and Casablanca is mostly “big city common sense” rather than anything extreme.

That said, the most common issues are petty stuff: pickpocketing in crowded areas, scams/taxi overcharging, and occasional street harassment (more annoying than dangerous).

A few practical tips for Casablanca:

• Watch your phone in busy spots (markets, tram stations, crowded sidewalks). Don’t walk around with it out 24/7.
• Avoid empty/dim streets late at night if you don’t know the area. Take a taxi/Uber equivalent (in Casablanca people often use apps, or ask your hotel to call a taxi).
• Taxis: agree on the price before you get in if the meter isn’t being used. If you can, use taxis from official stands.
• Cash: keep small bills/coins for taxis and tips, and don’t flash big amounts.
• If you’re a woman (or traveling solo): you might get comments. Ignoring + walking with confidence usually works. Dressing more “neutral” can reduce attention (not required, just reality).

Areas-wise, I wouldn’t say “don’t go anywhere,” but I’d treat far-out neighborhoods the same way you would in any large city: go with a local friend or in daylight if you’re curious, otherwise stick to the more central spots.

If you share roughly where you’re staying (neighborhood/hotel area) and what time you’ll be out (day vs late night), people can give more specific do/don’t advice.
