The Sultan Qaboos Grand Mosque in Muscat is a must-see architectural marvel, showcasing stunning Islamic art and design. The mosque is generally accessible, with ramps and designated parking available. Exploring the mosque independently is feasible, allowing you to admire the details at your own pace, but guided tours offer deeper insights into its history and artistry. Note that modest dress is required (headscarves are often provided for women), and the mosque has specific visiting hours, typically excluding prayer times and Fridays mornings. Expect to spend around 2-3 hours exploring the site. Admission is free, making it an affordable cultural experience.
