The complex is generally accessible, though some parts may have steps. Visitors can explore independently, but a local guide is highly recommended to appreciate its rich history, spiritual significance, and stunning Andalusian architecture, including intricate tilework and stucco. Open year-round, it's advisable to visit outside of peak prayer times. Entry is typically free, but donations are welcome, and guide services incur a fee. A typical visit lasts 30 minutes to an hour. Modest dress is essential for all visitors, with women often required to cover their heads.
