While Sicily is generally safe for travelers, it's advisable to stay vigilant, especially in crowded tourist areas. Petty crime, like pickpocketing, can occur, so keep your belongings secure. Research local customs and respect regional norms, particularly in religious sites. Areas with higher crime rates, such as certain parts of Palermo, should be avoided after dark. Always use registered taxis and stay aware of your surroundings, especially when using public transportation.
When visiting Sicily, it's respectful to greet locals with a friendly "Buongiorno" or "Buonasera" depending on the time of day. Dress modestly, especially when visiting churches, where shoulders and knees should be covered. Tipping is appreciated but not mandatory; rounding up the bill or leaving 5-10% is common. It's also courteous to wait for the locals to sit down before you take a seat at restaurants. Engaging in small talk and showing interest in Sicilian traditions can go a long way in fostering goodwill.
