The Hassan II Mosque in Casablanca is a stunning architectural masterpiece and one of the largest mosques in the world. Non-Muslims can visit via guided tours, which are available in multiple languages and provide insight into the mosque's history and design. The mosque is generally accessible, with ramps and elevators available. Visiting solo is possible via the tours, but exploring independently is not permitted for non-Muslims. There are no significant seasonal restrictions, but dress modestly (shoulders and knees covered). The cost for a guided tour is approximately 130 Moroccan Dirhams. A typical visit duration is around 1-2 hours.
