Not far from São Miguel Island in the Azores archipelago of Portugal, you'll find Vila Franca Islet.

This uninhabited green islet sits quietly just south of the town of Vila Franca do Campo.

Beneath its serene surface, this gem holds a lively past.

Once a volcanic crater, this islet is now a protected nature reserve teeming with unique marine life, including bird species like Bulwer's petrel, little egret and sooty tern.

The unique shape of this tiny island, sculpted by nature, makes it truly special.

At its heart lies an almost perfectly circular lagoon, linked to the sea by a narrow channel called Boquete.

Since the opening faces north toward São Miguel, it shields the lagoon from ocean waves and forms a calm natural harbour with a sandy beach.
