About Piedra Blanca Lighthouse
Also known as: Piedra Blanca (Isla San Marcos)
Piedra Blanca is a 15-meter-tall square pyramidal skeletal metal tower with a gallery, standing on an islet at the northwestern corner of Isla San Marcos. This islet shelters a small anchorage and is located approximately 25 kilometers southeast of Santa Rosalía. The lighthouse emits a white flash every 10 seconds from a focal height of 16 meters, visible for 12.2 nautical miles. The site is open to visitors, though the tower itself is closed to public access. Access to the islet and its facilities is typically achieved by boat, with the nearest port, San Marcos, being 3.4 kilometers away.
Why it matters: This lighthouse is essential for mariners navigating to the small, sheltered anchorage on the northwestern tip of Isla San Marcos, serving as a key reference point in this remote coastal area.
