When visiting Castelsardo, it's helpful to know that the town center is a limited traffic zone (ZTL), meaning most vehicles are prohibited from accessing it. This encourages walking or using public transport, so plan accordingly. The local bus service connects the marina with the town center, making it easy to explore. Additionally, Castelsardo operates on Central European Time (CET), which is UTC+1, and observes Daylight Saving Time (CEST), UTC+2, so adjust your schedule accordingly. If you're bringing electronics, remember that power outlets in Italy typically accept Type C, F, and L plugs, with a standard voltage of 230V and a frequency of 50Hz. Having the right adapters will ensure you can charge your devices without any issues. Lastly, a friendly greeting in Italian, such as "Buongiorno" (Good morning) or "Buonasera" (Good evening), can enhance your interactions with locals and make your visit even more enjoyable.
