Dress Code for Tourists: Modest clothing recommended but abayas/thobes not required for non-Muslims. Men: long pants and shirts. Women: loose clothing covering shoulders and knees; headscarves optional but appreciated in religious sites.
Prayer Times: Five daily prayers may pause business operations briefly. Many malls/restaurants remain open; heritage sites may have adjusted hours. Download a prayer time app for planning.
Photography: Avoid photographing government buildings, military sites, or people without permission. Heritage sites and public spaces generally allow photography.
Greetings: "As-salamu alaykum" (peace be upon you) is warmly received. Handshakes common; some conservative men/women may prefer not to shake hands with opposite gender — follow their lead.
Alcohol & Pork: Strictly prohibited in Saudi Arabia. Non-alcoholic beverages and mocktails widely available in premium hotels and restaurants.
