The Reserva Natural do Ilhéu de Vila Franca do Campo is a protected islet and marine reserve renowned for its unique volcanic crater lagoon, crystal-clear waters, and rich marine biodiversity, offering exceptional opportunities for swimming, snorkeling, and nature observation.
Located just off the southern coast of São Miguel Island in the Azores archipelago, the Reserva Natural do Ilhéu de Vila Franca do Campo is a small volcanic islet formed from a submerged caldera, creating a natural circular lagoon approximately 150 meters in diameter. This unique geological formation resulted from the collapse of the islet’s central volcanic cone, producing calm, sheltered waters ideal for swimming and snorkeling. The islet hosts a diverse array of marine life, including endemic fish species, corals, and marine plants, making it an important ecological habitat and a hotspot for biodiversity in the region. Above water, the islet’s rugged cliffs support a variety of seabirds, especially during nesting seasons. The reserve was officially established to protect the fragile marine environment and promote sustainable tourism activities. Visitors are drawn here to experience the pristine waters that contrast beautifully with the islet's rocky landscape, often enjoying boat rides from Vila Franca do Campo town, birdwatching, and underwater exploration. Due to its status as a protected natural reserve, motorized boats are limited, and swimming is only permitted inside the lagoon, preserving the area's ecological integrity. Its proximity to São Miguel’s main population centers makes it a popular day-trip destination while remaining a sanctuary for nature lovers seeking tranquility and rare wildlife encounters. The Reserva Natural do Ilhéu de Vila Franca do Campo stands as an exemplary case of volcanic island conservation combining geological wonder, marine ecology, and recreational appeal.
