The adjacent Castillo de Sancti Petri is traditionally identified as the site of the ancient Temple of Melqart-Hercules, where figures like Julius Caesar and Hannibal reportedly visited.
The beach is part of a tidal system that periodically shifts the channel, influencing the local sand distribution.
The former tuna fishing village (almadraba) at the site was once a hub of the region's historical bluefin tuna industry.
The island fortress contains a lighthouse that has served as a navigational landmark for centuries.
The seabed near the channel is a documented archaeological site, yielding various Phoenician and Roman artifacts.
Playa de Sancti Petri is a historic coastal site situated on the Atlantic edge of Chiclana de la Frontera, defined by its view of the offshore Castillo de Sancti Petri. The beach sits at the mouth of the Sancti Petri channel, which historically served as a vital maritime passage since Phoenician times. It features a blend of fine white sand, extensive dunes, and protected natural marshes within the Bahía de Cádiz Natural Park. The area includes the remains of an old fishing village, which was abandoned in the 1970s and is now largely repurposed for recreational and nautical use. Visitors can access the offshore island fortress by kayak, paddleboard, or boat excursions departing from the nearby marina. The beach is recognized for its ecological value, providing habitats for numerous migratory bird species. The site maintains a stark separation between its natural landscape and the urban development of Chiclana.

Monitor tidal schedules, as the currents in the channel can be strong and affect access to the island.
Bring water shoes if planning to walk toward the rocky island base at low tide.
Visit the local nautical center to rent equipment for reaching the castle rather than attempting to swim due to dangerous currents.
Attempting to swim to the castle is a common and dangerous mistake due to unpredictable and powerful tidal currents in the channel.
The beach is public year-round, but water-based excursion services to the castle fluctuate significantly based on seasonal demand and tidal conditions.
Respect the protected dune vegetation by staying on marked wooden walkways and do not disturb bird nesting sites.
