San Pietro A Mare Beach is located in the north of Sardinia, near the town of Valledoria, and stretches for approximately 3 kilometers. It is known for its fine white sand and crystal-clear blue waters, making it ideal for swimming, snorkeling, and scuba diving. The beach is surrounded by dunes covered with Mediterranean scrub, providing a scenic backdrop for beach activities.
The beach is well-suited for families due to its long stretch of shallow water near the shore, gradually becoming deeper further out. It is also a popular spot for surfers and water sports enthusiasts.
Visitors can enjoy watching sunsets and moonrises over the sea, and it is close to the mouth of the Coghinas River, an important habitat for various species of birds and fish.
