The Sheikh Zayed Grand Mosque in Abu Dhabi is a breathtaking architectural marvel and one of the world's largest mosques. It welcomes visitors of all faiths and offers free admission. The mosque is highly accessible, with facilities for people with disabilities. Visiting solo is easy and common, with readily available information, but guided tours offer deeper insights into the mosque's design and cultural significance. Modest dress is required (easily addressed with provided abayas for women). It's open daily, except during Friday morning prayers. A typical visit lasts 2-3 hours, allowing ample time to explore the vast courtyards and intricate interior. Photography is permitted in most areas. Consider visiting during cooler months (October-April) for a more comfortable experience. Expect to spend little to no money, as entry is free, but plan for transportation costs.
