The best area to stay in Castelsardo is within the historic old town, known as the "Castello," or just below it, near the marina and Lungomare.The Castello area, perched on a promontory overlooking the sea, is Castelsardo's most iconic district. Its narrow, winding streets lead up to the Doria Castle, offering panoramic views of the coastline and the Gulf of Asinara. This area is characterized by its medieval architecture, small local shops, and traditional restaurants. Couples will particularly appreciate the romantic setting, the stunning sunsets from the castle walls, and the quiet evenings walking through ancient alleyways.For travelers seeking convenience closer to the water, the area just below the Castello, encompassing the marina and Lungomare (promenade), is an excellent choice. Here, you'll find easier access to the harbor, local beaches, and a wider selection of hotels and eateries along the seafront. Families often find this location ideal due to its proximity to the water for swimming and boat tours, and the flat promenade is convenient for strollers.
