Spiaggia di Maria Pia is a beach located on the north coast of Sardinia, Italy, near the city of Alghero. The beach is characterized by its crystal-clear waters and fine white sand, making it a popular destination for tourists and locals alike.

The beach is named after the nearby Maria Pia Tower, a historic tower built in the mid-19th century by the Kingdom of Sardinia to protect the coast from pirate attacks. The tower is now a popular tourist attraction and can be visited by the public.

The Spiaggia di Maria Pia beach is around 1.5 kilometers long, with an average width of 30 meters. It is surrounded by pine forests and sand dunes, providing a peaceful and relaxing atmosphere. The sea water is shallow and warm, making it ideal for swimming and water sports such as snorkeling and windsurfing.

The beach is well-equipped with facilities including restaurants, bars, and water sports equipment rentals. There are also beach umbrellas and sun loungers available for hire. The beach can get quite crowded during peak tourist season, but it is still possible to find a quiet spot to relax and enjoy the beautiful scenery.
